I have been on zoloft 50mg for about 8 weeks now. The first and very bothersome side affect is the problem sleeping. After getting to sleep, it is very hard to stay asleep. My nights are full of vivid dreams. I have read this is a normal side affect. The BIGGEST problem I've begun to have is that while sleeping...I guess I am dreaming that my skin is itching because I have woken up many times to the pain of me scratching my skin until I have left deep burning scratches. Last night I had to get up and get a cold wash cloth to put on the skin on the back of my neck from the harsh scratching. This has NEVER happened to me before the zoloft. It has made a world of difference in my depression, and do not want to have to go off of it. Has anyone ever heard of this? Please post if you have....need to know this is a side affect...not just me...
