That’s not good man, it’s difficult for sure as I’ve seen people in various states of that and it’s different for everyone but equally challenging in their own right.
One of the things, thinking about the situation as a whole, perhaps you could add in some additional vitamins, even simple and inexpensive ones. Vitamin D with vitamin K is shown to do incredible work at removing calcium plaque in the vessels that build up over time. Those plaques can cause cerebrovascular accidents, it sounds like the one you had in the past was more on the aneurysm part rather than constriction but it could help! There’s a lot of good and promising research out there in that regard and the combination is usually not more than 20 or 30$ for a 60 day supply. I know you likely take all kinds of shit but some of the basics could go a long way!
As well, the people around you may not enjoy it but adding fresh garlic into your diet at one bulb a day is proven to do wonders for blood pressure and that corresponds to brain health since a common occurrence for people that end up with neurological episodes and issues is high blood pressure that causes weakening of the membrane in one of the vessels. Being able to assist our body at lowering the blood pressure goes a good way to reducing the risk overall.
You may think both of these are horse shit but I have experience with these types of things myself in my own health and with my wife and her health issues, so my anecdotal evidence suggests it does well. But then someone could say that lifting your right ankle and touching your left ear and farting will fix an issue so take it for what it’s worth! Lol
