Ok so I'm in Africa and doing pretty well considering we can't have the water from the tap as it's not clean so been having filter water all that's fine slept well first night. But last night I just couldn't stay asleep.
tossed and turned and at 5am got up as felt unwell. Had anxiety untill it settled down an hour or two later.
Thought nothing more till later that morning whilst out in the sun I suddenly became so dizzy it was horrible.
it was this sensation before you vomit so I thought it was coming I panicked and then climbed into the bus breathing.
I wasn't sick but had a yucky tummy.
no cramps but. Loose stools and tired.
now I feel yucky
still I've had an uoset
stomach sachet and taken a tablet for d*. But still feels full and blegh I've not got cramps but wish it would ease I've not even been hungry.
does it sound like noro? Or sunstroke) (I keep getting hot flushes)
soooooo scared
