I take on pill every morning and don’t really think about what I eat. :)

I use just the basic over the counter allergy medicine. (Kestox is the product here) It costs about 15€/100 tabs, so much cheaper than DAO suplements.

I used to have mediocre IBS symptoms. Never to the point of being debilitating, but such that I was always aware where the closest toilet was and got anxious if it was too far away.

There was an article about studies being done on using common antihistamin to treat IBS that helped in many cases. Tried it and never looked back. That pretty much solved my bowel ussues.
