"i got diagnosed with chronic fatigue syndrome 5 years ago. the doctor put me on many different pills which made me sick to my stomach. then he put me on phendimetrazine. i take one when i wake up and one around 3pm. it has helped me have the energy i need to enjoy life. i was always so tired and didn&#039;t know what i was going to do. i am so thankful for this medicine.  i have had no side effects except for dry mouth sometimes. i drink more water and chew sugar free gum to help. i don&#039;t take this for diet. i&#039;m 34 and 5&#039;6 weighing 134. i&#039;ve maintained this size for 5 years now, give or take a few lbs. it really helps for energy."
