Hi, I am on medication for depression. I am having Prozac 20mg. After having this tablet I am shoving terrible physical and emotional symptoms. I know that, I started this medication to reduce my depression but now it has adversely affected me. I started Prozac 3 weeks ago. I feel that this medicine has caused anxiety and major loss of appetite along with nausea. From last 5 days, I am taking Doxepin but it is causing dizziness. As the result of these medications, I am anxious about my mental state. I am planning to undergo cognitive therapy for depression from a clinic in Toronto Will this treatment also have side effects? I have lost my sleep for last one month. How long will it take to cure? Is there any medication required for this treatment? Have anyone undergone this treatment? If yes please help me out.
