sorry to hear of your troublesI'm back to trying it again but at a miniscule dose. If my blood pressure rises again I will try a herbal remedy to lower it. So I started with one drop in a glass of orange juice, and drank one quarter of it. That's pretty low. I took it in orange juice - a tip from the Ray Peat forum. I will take a dose once every two days.
many people in the lyme and associated diseases community have this type of ultra sensitivity to anything antimicrobial (like Methylene blue).
as above - effective doses for infection are much much higher
i am moderately sensitive and had to start on 10mg / day - and gradually ramp up to 120mg / day over some months
if you are ultra sensitive you will likely find it very hard to get to even nootropic doses.
in many people with these infections ( I do not know if your case is due to infections so just providing information) they find that their strong reaction symptoms are driven my MCAS that is caused by the infection and that they need to get this under control before they can effectively treat the infection with antimicrobials.
people find a combination of MCAS stabilisers, low histamine diets, antihistamine drugs and brain retraining exercises helpful for that
