This is one of many disagreements me and my mum have. Never been big drinker but do like a few drinks if out with anyone other than my mum. I was told after my brain injury not to drink any alcohol for first year which purely cos of risk of seizures I did stick to. After the year I did occasionally have a few drinks. I don't feel it effects me any more than it did before. My mum can usually tell if I've had much so I would say it effects me more than I notice.
