"adipex(phentermine) is great for weight loss.  i did experience minor side effects (i.e. dry mouth, insomnia.) i have taken this medicine on and off for several years.  i noticed rapid weight loss the first time i took it, losing over 30 pounds in the first month.  i was 202lbs when i took it the first time and after only 1 month i was down to about 170lbs.  i went off of the medicine for several months, didn&#039;t exercise and returned to my original eating habits, regaining all of the weight plus some.  the second time i took it i didn&#039;t experience the same rapid weight loss i had with the first attempt, only getting down to about 182lbs. going for try #3 but will do it right this time with exercise and diet change for life!"
