Ok, so there is a way I'm knowing my anti-MCAS pack is working, this is something I also discovered with Ketotifen. Apparently, all these years of histamine release in my brain gave me a form of histamine tolerance. After I take the pack I start feeling sleepy. Like today I only took Quercetine and Luteoline without the anti-histamines and that made me sleepy as fuck. I've also noticed that with Ketotifen. Now I know that Ketotifen is known for inducing sleepiness, but in my case it cripples me. I've known people from MCAS FB group who say that Ketotifen barely does anything to them. So perhaps this is a good thing? I'm reducing all that histamine that is stuck in my brain? IDK.
