I started taking wellbutrin sr about two weeks ago. I (cut)quarter the 100 sr and take only 25 mg. Once in the morning. This is the only antideppressant that has helped me considerably. I feel like getting up in the morning. I have good energy. I stay focused. I am 98% better in my impulsive behavior. My mood swings are 80% better. The only things I don't like are i've gained 7 pounds and I did experience constipation which has gotten a little better.I'm not eating any more than usual and I excersice plenty. I heard if you up your dose it might balance out. Has any one else expeienced this and does your body usually re-ajust???
