For me a MCAS reaction often feels like food poisoning that comes on really hard and fast but only lasts about an hour or two instead of a day.
I found that the supplements I was taking that helped with other conditions were triggering the MCAS reaction when they hit my stomach if there wasn’t enough food with them. Getting the amount and timing was too challenging until I found the Orgain Protein Shakes (ThriveMarket has good prices on them).
I also call the MCAS reaction a histamine dump – the mast cells dump too much histamine into the system at once and can cause any symptoms that allergies can – which are immune system processes overreacting.
The “simple but not easy” (is there a word for that?? I want a word for that, I don’t care what language – to do, search) answer is to reduce the toxic load my body is coping with and increase the nutrients I’m getting.
Cutting all sugar and processed foods would be a major step in that direction. It’s also why I try to be eat low or no gluten and low dairy consumption.
