I've been on seroquel a few months now. My dose has slowly been increased, and now I'm at 150mg at night everyday.

I OD'ed on it back in July, went to hospital and was fine, but whilst there I had a strange feeling in my chest, like I wasn't breathing properly and couldn't breath in the way I needed to.

But since i've had my dose increased from 100 to 150mg I've been getting this feeling in my chest about 30-60 minutes after I've taken it. Kind of like the feeling you get at the beginning of a panic attack. It doesn't usually stop before I get to sleep.

I've recently started a new job and can't see my psych or doctor for a while really so I'm not sure what to do. I've never seen this sort of thing mentioned on the side effects, but it worries me. Any one else experienced this?

(I'm also on 200mg of sertraline a night btw)
