Just got out of the bath. The water was a bit cooler i think this time and i was sipping water but i only lasted about 13 minutes through worrying i’d have a repeat of yesterday. I sat up and let some water out before putting the plug back in and filling it with cold water. Then i laid back down for a couple of minutes. My heart was pounding but not as much as before. When i stood up I was nothing compared to yesterday and then i had a cool shower.
A big difference. Thanks everyone.
