I have PTSD/anxiety/depression. Was told by psyc doc that Zoloft is for PTSD. Started with Lexapro made me sick lost weight, went to Celexa, same, went to Wellbutrin as it worked before the PTSD, but gave me horrid anxiety and more weight loss. I started Zoloft 50 mg 10 days ago, dizzy, nausea, shakey, sleepy, anxiety, insomnia. Doc prescribed xanax for anxiety and lorazepam for sleep. I take 1/2 of each. But need encouragement that the side effects will decrease soon. I can not afford to loose anymore weight but do not want to give up.
