Thanks Sammi, heather and annabel for the reply.
I know some unfiltered wheat beers make me flush, so definitely an allergy on that for me. I also know that when I've had more than a couple beers it seems my body reacted differently when on the PM than when not. Woke up in the middle of the night burning like I had a fever and really thirsty on several occasions.
I did see the Endo last week, but this is for my thyroid level checks which were fine. I was concerned that PM would effect these levels but it did not (at least based on blood tests). Perhaps it's interacting differently with me because I have no thyroid, or perhaps it's all in my head.
Read here that PM possibles reducing desire to drink...

WebMD though says it is used to treat alcoholism and hangovers...

and of course Ainterol warns right on the side to not take when consuming more than one drink of alcohol.
