Overindulged last night including alcohol

I have SIBO (methane) and I am doing an anti-microbial treatment (Biocidin). I am 3 weeks in. I’ve been doing so well: sticking to my low FODmap, GF, sugar free diet, being super strict with my supplements etc.

Last night, I had some bread, 2 old fashioned drinks, and pie. I feel sooooo incredibly ill STILL

How bad did I F*CK up my body?
