I am on 150mg Effexor Xr, and take 75mg 2x a day. I did not take it for 2 days due to BS insurance reasons. I felt completely dizzy and off balance for those 2 days. Could not figure out why. A very weird feeling like I was drunk! Is this normal for missing 2 days of this? This is the only thing I can think of that made me feel like that. Got back on it today, and no dizzy spells. Anyone have this? Guess I wont be skipping any doses!
