I am on Wellbutrin SR 150. They started me at 1 pill once a day. After three days to 1 pill 2x a day. Last night was a "clutching my rosary" moment. I fell asleep and woke up a couple of hours later to go to the bathroom. I had INTENSE ringing in my ears - like a freight train. I was very dizzy. By the time I got down stairs and went to the bathroom I was so dizzy and disoriented I knew I couldn't stand up much longer. I ended up crawling around on the floor praying with my head down on the floor. I had HOT, I mean like FIRE sensations shooting up from my abdomen to my head. These subsided more and more over the night as long as I kept my feet elevated and lay flat on my back. Has anyone had ANYTHING like this? This is just AWFUL. It hasn't been a week yet, but I'd rather be seasonally sluggish than EVER go through this again! I am waiting for my doctor to call me back today. I did NOT take a pill this morning!
