I mean this only as a helpful bit of information that might or might not be
relevant to your case at all:

along with bipolar II and allergies that are inherited, I have an inability to
break down disacharrides in cow's milk. I thought my daughter had the same problem when she was young and recommended that she try Lactaid tablets (which are a form of lactase which breaks down a disaccharide into glucose.)

She tried it but her ability to break disaccharides was so strong that she began having racing thoughts. We never suggested that she try it again.

It could be that if you drink cow's milk you may be breaking the disaccharides so well
that it is causing a type of "brain allergy". You may be having racing thoughts from
that. If you do drink a lot of cow's milk, try cutting it out for about 1.5 weeks and
see how you are; if it works you'll know that you need to be careful about cow's milk.

It's possible that it could be the sugar in some other type of drink that you can't break
down. In that case, try removing that one for 1.5 weeks and see it if works.

Otherwise, I don't know how to help. I don't experience racing thoughts unless I'm about
to be involved in a circumstance that calls for quick thinking and fast action--like an
automobile accident.

Good wishes, Blue Mountain.
