I am fairly sure that I am feeling like this as a hyperemesis thing rather than side effects.
I took my first citalopram last night at about 6pm, was sick at 7.20pm (not unusual, was feeling very sick earlier but managed to hold off as I wanted to give the pill plenty of time to work).
Managed a very quick bath after that, the world was spinning.
Crawled (literally) from the bath to bed and stayed there all night drifting in and out of sleep. The one time I managed to move to go to the loo (and be sick) I had to move extremely slowly because of the spinning.
This morning I am still being sick (again, not desperately unusual but more than usual iyswim), head is pounding, and everything is fairly spinny again - am worried about being alone with DC tbh.
I have no idea if this is all down to the sickness (it had eased up to "manageable" before now), or very quick pill side effects. I don't even know how long the pills take to process and if it had time to get into my system before being sick yesterday!
All I know is that I feel like hell.
(sorry for the length)
