Sleepsex symptoms and conditions

I was put on Zoloft 4 months ago to help me deal with the stress and trauma I went through caring for my dieing mother while I was pregnant with my 5th child.

However it has just about killed my marriage. I think it's great, I feel better able to cope with things, I don't feel that overwhelming feeling of losing control and wanting to run away from my children and husband. I thought it killed my sex drive too but since i've been on zoloft I have started having sleep sex which is not good. If it was my husband I was having it with it would probably be ok, but it is with myself and it is causing major problems. I have no recollection of any of the instances, and it has increased when I upped my dose from 50mg to 100mg. I had told my husband for ages that I had no desire for sex whatsoever but lay next to him every night having sex with myself. Now I am extremely embarrassed and ashamed and feel alienated as I have no one I feel comfortable in sharing this with. I can only hope that my husband loves me enough to stick with me and support me through this while I come off the drug. If I had of known before hand I would never have gone on it.
