I felt fine leaving work Thursday afternoon.
By the time I got home I had terrible stomach cramps, and had diarrhoea all evening. (Sorry! 
)
Felt completely washed out and spent the day in bed Friday. (Not like me at all.)
I can eat now, have had no more diarrhoea since, but I still feel unwell (no-where near as bad as I did, mind you), but am now feeling hot here and there. My gut still feels a bit tender. I've been able to potter today, but have no energy and feel weak and watery iykwim.
(I am menopausal, but my hot flushes have died down a lot now.)
The original diarrhoea could have been a reaction to an anti-inflammatory but I haven't taken it since Thursday am in case it is.
I wouldn't even ask usually, but we are seriously stretched already at work, and my absence will mean colleagues will have an additional workload.
Do I call it now?
See how I feel in the morning?
What would you do?
