"i have only been on adipex for a week and a half now,and lost about 4 pounds in the first 3 days but now i am at a stand still again, i am on 37.5 dose and have never experienced jitters, extra energy, and worst of all i am still hungry! i do not eat that much in hopes i will still loose weight, also i work out at home for at least an hour 3-5 times a week, mixing cardio with weights. i only have the prescription for one month so we will see how the other 2 1/2 weeks go."
