"i gained a lot of weight after having my 1st son and a failed iud. my doc prescribed adipex 37.5 and i took it 5-6 days per week for 5 months. in the beginning it gave me extreme dry mouth and it was hard to fall asleep because of the energy boost but it suppressed my appetite a lot and if i ate to much it made me vomit.  i started working out slowly a few times per week and by the time i stopped taking it i was working out 5 days a week. i am 5&#039;8 and my start weight was 195 my end weight was 137.after my 2nd son i lost the weight easily and got back down to 140 but after my daughter i gained and could not lose anything, my energy was low and i could not control my appetite.  as soon. as i am done breastfeeding i will be taking adipex again"
