The rash was minimal. Tiny Pin size red bumps all over my torso & back. I had splotchy red areas on my legs. No discomfort it itching.
My doc just told me to stop immediately. It took 3 days to clear up. Then I had a few withdrawal symptoms. A panic attack at work, which sucked major. Though, I was only on it a few weeks. I was only up to 75 mg.
I did not like the side effects from it all. It did not agree with me. But everyone is different. Most people love it.

Lithium has been by far much more agreeable. I really like it. And I've read others who had a horrible time. So you just never know until you try.

I pray you get lucky & have a good outcome. Those 2 seem to be the best to start with.
