I've been on prozac (started off with 20mg) for four days, just got prescribed it for anxiety , and the huge list of side effects have spooked me. I've been getting headaches for the past few days (to be fair those started the day before I got prescribed the prozac) and since yesterday I've had this weird feeling in my head like my brain is fuzzy. It's kind of a tickling feeling behind my eyes and in the side of my head? I feel pretty hazy aswell. Are these normal side effects to be having so early on? It's freaking me out a little and triggering my anxiety. Anybody else have that kind of thing? Like a weird feeling in the brain? It could just be from the 2 month long build up of stress, or normal side effects, or a mixture of both. Just feeling pretty weird.
