Hi been on 37.5mg of Effexor for two weeks had a few sideffects but nothing too bad, but I increased my dose today up to 75mg and I am feeling more anxious and the scared thoughts have came back also gave some really bad palpitations, can anybody tell me if they had the same when increasing their dose and how long this will likely last for? It's maybe just me being paranoid and expecting to get this but I'm not feeling too great at the moment
