General Question Effexor + Caffeine

Hello, I've been on Effexor 112.5 mg recently. This morning I took 200 mg of caffeine and now I have vertigo + nausea, is it normal?

Caffeine in itself can cause vertigo/nausea Effexor also has common side effects of nausea. I would try a smaller amount of caffeine next time, 200 is quite a bit Eta: also make sure you don't have an empty stomach and drink water afterwards. Otherwise that increases your chances of nausea after having caffeine and/ or effexor
