There's nothing so bad a drink won't make it worse Stewy.
There are people who are extremely allergic to things like peanuts or seafood, or gluten or lactose intolerant. I've realised lately I can no longer eat cashews or KFC cos they both mess me up with IBS.
Just a fact of life, mate. I'd rather not be able to take alcohol than something like an allergy to processed food for example.
Have you explored any possible solutions beyond your GP?...sorry I know I should know but there's so many members and stories here it's hard to remember.
