"This is the best diet medicine ever.  I have been taking this pill for years.  I generally take it two days on and one day off for efficacy and it has worked.  When I first started taking this medicine I did not follow any type of eating plan and would stop and gain all my weight back.  That made me realized I had to use an eating plan of my choice, like weight watchers.  Low carb diet is my choice.  This pill has taught me how to eat also.  I ate sweets all the time before this pill and now eat a sweet only the day I do not take the pill.  I recently went off Adipex in December because my doctor feels my heart rate was high (103, 115, etc.)  I went back on them and monitor my heart rate because I gained 15 pounds.  No other medicine out there like it."
