Hi - I have been on Effexor XR for 3-4 weeks...in the beginning, I was very anxious, nervous, etc., but stuck it out and was OK after a while. I finished all the samples my dr. gave me, and filled the scrip for the generic version that he gave me (I asked for generic, because it's cheaper). I took the first one 2 hours ago...I'm sweating, my hands are numb now like I'm going to have a panic attack, and I cannot catch my breath due to nerves

...these pills are not extended release, and I'm wondering if that's got anything to do with it...? Any thoughts would really help - thanks.
