I got through long phases where I vomit every morning even if the food from the night before goes through. I know the intense nausea could be triggered by my POTS some mornings but now its normal for me to cough up froth. And if I drink any water after It turns to more froth. I dont know if this is normal for GP or not but Im sick of it and want ideas on how to minimize this. Do you have this and what do you do for it?
