On average, people lose at least one pound of weight per week. If for some reason you feel something out of ordinary or you fail to lose weight, Phentermine might not be working for you and you need to address that issue with healthcare professional. Some people may experience Phentermine side effects and further tests will reveal the reason why.

​There a lot of Phentermine makers worldwide. Some are simply filling capsules with powder and selling it at the local pharmacies as generic (non-branded) Phentermine. There also Phentermine makers that are offering branded products. The difference is release mechanism or addition of other ingredients.

If you are purchasing Adipex P or Qsymia, you are looking at a lot higher cost. Bottle of Adipex P can range from $100 to $300 per bottle and Qsymia between $300 and $500 per bottle. The cost is 100% out of pocket as no insurance company pays for the Phentermine diet pills.

How much weight can I lose on Phentermine and why I am getting fat?

​How much weight you can lose depends on several factors. Some of the major ones are metabolism, eating habits, active or inactive lifestyle, overall health and other medications, vitamins and supplements you are taking. For example, people with hypothermia, may not take as much Phentermine as healthy individuals. People with diabetes, may have sugar spikes as one of the Phentermine side effects. Patients who take other medications can react negatively, where Phentermine results may not be as expected. The most important ones are eating and moving, being physically active. You absolutely must follow proper diet and exercise regularly while taking Phentermine. At minimum you should be able to lose one pound per week. If that’s not the case, you might want to stop and go see a doctor. Always remember that full spectrum of nutrients and vitamins must be consumed daily. When you are dieting, you might not get enough nutrients and you may experience adverse effects, rather than benefits. Make sure that you are consuming vitamins and nutrients from other sources than food. Ask your doctor, along with Phentermine, what multi vitamins and supplements you need to consume daily in order to maintain good health. In order to physically function, human body requires 2000 calories per day. The formula is simple, if consumed less than 2000 calories in one day, human body is programmed to “borrow” nutrients stored in these cells. Consuming more calories – body is programmed to convert sugar into fat and store that fat for the future. When you exercise, you end up “burning” additional calories, which will result in more fat being “borrowed” from these fat deposits. Every human is born with hundreds of millions of fat cells designed for storage of fat so that body has enough energy to function if lacking needed amount of nutrients. These cells are designed to fill up with fat and grow 1000 times of it’s original size. When cell reaches it’s capacity, it clones another empty cell and so on. That’s how people get fat. These cells gets filled up, similar to water balloons and multiply. Everything you eat, converts into sugar for the absorption. Food that comes with higher glycemic index, creates these “sugar spikes” and any excessive amounts of sugar eventually converts into fat. Food that’s high on carbohydrates, generate these spikes, where pancreas releases extra amount of insulin for proper absorption. Any type of food with high glycemic index, must be avoided at any cost. Fiber is a must with every meal. It slows down that absorption of sugar and prevents spikes. Always remember, if you don’t consume enough fiber, you are looking at higher insulin levels that will eventually become fat. Stay as far as you can from “empty calories”. Soda, especially diet is the worst possible cause of weight gain. Alcohol, especially beer must be avoided while you are dieting. Obviously, anything deep fried, potatoes, burgers and any kind of fast food must be forgotten. Following everything with consciousness and discipline about your daily regimen will get you what you need – health and weight loss!

What type of side effects people experience on Phentermine?

​Phentermine side effects are not out of ordinary compare to other stimulant based medications. You may experience nausea, headache, stomach cramps, insomnia as mild side effects. More severe side effects may include vomiting, fainting, memory loss, erectile dysfunction, addiction among other health complications. In case of experiencing mild side effects, at least contact your healthcare professional to let them know about how you feel. If for some reason you are experiencing something more, do not hesitate and call 911 immediately. If for some reason you are concerned about how you feel while taking Phentermine, stop and wait until your doctor clear things up for you.

Where can I find Phentermine coupons?

​Often, either brand makers or local pharmacies issue coupons to buy Phentermine. Normally these coupons are issued due to over stock or low demand seasons. Summer time and time around winter holidays will be the best to get cheaper Phentermine. During summer and winter, weight loss industry goes down, because people are not as concerned about weight loss during these periods. When people become more concerned about their weight, normally after New Years, prices are “skyrocketing” and it might be expensive to buy Phentermine during that time. So if you plan your New Years resolution, it is better to get your supply before the Christmas and begin taking it after New Year. You can save as much as 50% that way.
