I've been on Effexor XR for almost two weeks. One week at 75 mg and 5 days at 150 mg. I switched from Lexapro, which I'd been on for 10 years. I felt ok the first week at 75 mg. but the 150 makes me nauseated. I'm wondering if I need to taper back down to 75 or since it's only been 5 days if I can just go back to 75? Or if I wanted to stop this medication would I need to taper? I've heard bad things about getting off so I was thinking about just trying something else.
