Hi. I'm 27, male, and have been diagnosed with partial dysautonomia. My primary symptoms are fast heart rate (esp. after eating), fatigue, brain fog, frequent urination and chemical sensitivity. After some convincing, I just started on Effexor a few days ago (a friend of mine had/has a bad experience with this drug, and I was wary of it). But the Effexor is making me sick (haven't thrown up, but I felt like it) and feel very strange--it makes me giddy for a while, then I get very sleepy, but when I try to sleep, I can't. It also seems to be increasing my paranoia about things. I started out at 25mg bid, today went up to 37.5 bid. Do these side-effects go away eventually? I sure hope so.
