"during my pregnancy i put on about 50 lbs! now i&#039;m trying to get it off. just started phentermine up again a few days ago at 194 lbs. i work out at the gym 2-3 days a week doing cardio and weights. i also walk about 30 minutes most weekdays during my lunch break. i already feel my clothes fitting looser. i get very jittery, have dry mouth and insomnia. i will stick to it because i have had excellent results with it in the past. in 2007 i lost over 50 lbs in about 6 months. my target range is 140-150 this time. so i am wishing all of us luck. please remember that once you get off the medication it is very easy to put the weight back on unless you really work at it."
