I've never found any hard evidence alcohol has any effect on MS, although I imagine it isn't ideal considering it generally isn't good for you! However, I do enjoy to drink in moderation. I drink quite regularly but of course, with the MS fog, I am very strict with moderating to as not to add any extra trauma the next day!
I have wondered if anyone notices much difference with or without? I sometimes feel hungover, just from the cognitive fog symptoms anyway, so have tried and tested drinking or not. I woke up today after a period of not drinking and felt almost worse than some days when I've shared a few bottles of wine the night before!
