Hi! (Good morning here!!)

I've been feeling sick for a few days, 3 so far. No vomiting, but feel like I might sometimes. Generally it's like morning sickness (but I'm NOT pregnanat! lol) Every now and then I feel really bad, cold sweat, ready to run to the loo etc.
I'm not on any new meds, haven't changed brands. Can Hydroxychloroquine suddenly make me feel like this? Am I just overtired and this is a new symptom?
Ideas on a postcard!
