Effexor. Now I am on 150 mg. of bupropion, 1 mg clonazepam and 37.5 mg of Effexor. My pdoc said he will gradually wean me off the clonazepam. I take the clonazepam for insomnia and I am wondering if I will be able to sleep without it and how bad the withdrawal will be when he stops the clonazepam. Has anyone had any experience with these drugs?
