I have been taking wellbutrin 100mg SR for about six weeks now. The first two days were the worst, my heart would pound and I would feel very irritable and sometimes violent during the day. In the evening when it wore off I would feel very sad, sometimes feelings of complete despair. On one occasion I spent 15 minutes laying in the floor of my bedroom crying uncontrollably. After a few days these effects wore off and I have felt a lot better about things. I no longer dwell on negative things, I am able to move on and I am happier in general. This morning I took my pill at 8:00 and fell asleep and experienced very clear, vivid, lucid dreams in which i would wake up (in the dream) and move on to the next dream, realize it was a dream, and then wake up again(in the dream) I couldn't tell if I was awake or dreaming. However, this is the first occurrence of strange dreams. Overall, this medication has helped me a lot.
