I cold-turkeyed Lamictal because I got the dangerous rash and don't remember many withdrawal effects, but that was a rough time in my life anyway and I don't remember a lot. Also probably I didn't care about withdrawal because I had a purple rash that felt like a burn and just wanted it to go away.

Withdrawing from Zoloft was the worst one for me, I felt horrible. And my mom says Effexor withdrawal is pretty bad too.
