After 12 years of taking effexor and feeling like crap for the past year I've gone cold turkey for nearly 4 weeks.

I've now got bad muscle tension and have been exercising/relaxing etc to help it in the hope it will go but it doesn't seem to be improving. Can anyone help me with some advice - is this still effexor withdrawal or is this really how I'm going to be from now on as I can't bear it!?

Thanks
