I've been reading all the horror stories about effexor and have been doing so for many years, especially about weaning off of it. For the last 6 months to 1 year I will sleep without waking up for nearly 24 hours if I miss a dose of my meds. It used to be just those brain zaps driving me nuts but now I'm comatose! I'm not sure if its the effexor alone, or in combination with the wellbutrin, and/or gabapentin that is causing this. I was diagnosed with severe sleep apnea over a year ago and will experience this excessive sleeping even while using my CPAP machine. I was wondering if anyone else is gone for anything similar to this? I am curious.... My main issue now is thinking I need to taper off and go off my meds (with my doctors help of course) before I get pregnant. Any suggestions from people that have withdrawn from Effexor, and/or the other meds? How did you cope?
