Hi I've been taking sertaline for six/seven weeks at 50mg and last week my doctor put them up to 100mg. Since yesterday I've become extremely hyperactive and bouncing off the walls. I find really random things hilarious, I have been singing everything, my thoughts are super fast, I've been jumping about and thinking things like I could jump off the roof and be fine. Normally thoughts like that would make me upset but I think it's all great. I feel really wired basically. It's a very nice feeling and I feel extremely happy. Has anyone else had this side affect from sertaline? X
