I've recently started 16:8. All going well. Had an evening 'off' to have dinner and a drink with an old friend. Had literally just one glass of white wine. But that made mt head spin and I felt awful! I have low tolerance for alcohol anyway, but this was unreal. I wasn't drinking on an empty stomach - I'd had lunch and dinner (decent amount of calories too). What's going on?? Does fasting cause low alcohol tolerance (even when drinking when not in a fasting time), and if so, why?!
