Trying not to go unconscious at 2:15am

I woke up Thursday morning at 2:15 am and quickly knew something was wrong; if I didn’t act fast I was going to go unconscious for the eighth time. I threw down some Zyrtec and Benadryl, put some ice in a towel, went outside, and sat down with my head between my knees. (When I get close to passing out I feel extremely warm, like some form of hyperthermia, so I try to cool down as fast as possible.) I don’t even know what I did wrong this time, but that’s how life with MCAS rolls.
