OK, now I think I genuinely am experiencing night sweats... I've woken up clammy for the last couple of nights, and deliberately wore light cotton pyjamas so that's not a factor.
I wouldn't say I was 'drenched', but my pyjamas and a bit of the sheet under me were a little damp.
I know this can be a common side effect of sertraline/Zoloft (I'm on 100mg), but I started taking this before Christmas - could the night sweats side effect kick in suddenly?
Coupled with the weight loss, the bloody streak-on-a-stool, and the bloody saliva, I'm working very hard not to freak out. I've managed to regain a bit of weight - about 2 or 3lb over the last couple of weeks - and the bloody stool/saliva hasn't recurred again. I'm not fatigued or feverish, and I don't feel like I'm coming down with anything viral. My appetite is fine (when I'm not being anxious).
I am waiting on my chest X-ray results, and assuming that no news is good news - I was supposed to get them within one week, and it's been longer than that now. I could go back to my GP, but I think they're sick of the sight of me and I feel like they rarely take me seriously, due to being younger and (possibly) female.
