I stopped after 6 days and didn't have any withdrawal symptoms. I was just so relieved to be rid of the side effects. A headache would have been more preferable. Take some Tylenol or other pain reliever to get rid of the headache - I'm sure you'll be fine.
keep riding it out. if the symptoms persist after a few days checj in with your Doctor. I have been on Lexapro for a couple years, and before that paxil. I haven't heard of too many problems after just a few days. Good luck, and i hope you feel better.
