I wasn't quite so lucky with my SSRI's, i ended up having tremors (that got immensely compounded by energy drinks, my entire body was shaking), nausea, nilly willy ability and panic attacks. Began weaning off immediately after the panic attacks, didn't want to deal with that shit. Ironically, i've actually felt a lot better since i stopped. Side effects besides, it could very well be that the treatment/episode knocked something back in place in my head, because i feel like i've come out of a minor depression. I've also had a couple of fairly bad panic attacks post cessation though (one lasted two eternally long hours and fucked me up so much i was still reeling the following day), but i'm pretty sure that's just my anxiety getting stuck in a loop now that i know how bad it can get. :V
As for something happy though, i think i might finally have gotten a minor epiphany regarding said anxiety: I've been going at it all wrong. I've thought of it as an enemy, a bad part of me that needed to be beaten into submission and excised from my very being. Indeed, beating down an enemy does hamper its efforts sometimes, but also makes it redouble its efforts to get back at you. But, i've realized that it's not an enemy. It's a scared and sometimes hysterical child. You don't fix that by yelling at it to shut up. Instead, what i need to do is to work with it. Bring the scared little scamp close and let it calm down on its own. Agree that the metaphorical sharks in the metaphorical water are scary, but you're in a metaphorical boat, so jumping overboard isn't going to make them less scary.
Now obviously, for more severe cases of anxiety than mine (which only gets really bad when feedback loops enter the picture), this might not be effective, and it has had the effect of making me feel the gut tingling sensation noticeably more often (might also be aftershocks from the previously mentioned Dire Panic Attack(tm) which happened monday night), but the point is that it doesn't really affect me like it has done before. I've even managed to halt an incoming panic attack this way, even if it was the exact same initial sensation as what kicked the big one off. It is of course a LOT tougher to maintain that mindset once a panic attack has actually started though, i'm sure many of you know how much they can warp your thoughts while you're going through hell.
