I was never a big drinker apart from Euro 96 when it all got a bit messy for a month and now I'm in my 40's I can't even have a mouthful with dinner without feeling sick for hours. It's like I'm poisoned by it
.
Health wise I'm fine, go to the gym, eat a mainly veggie diet, blood is always fine... etc. Always exhausted though because I'm a LP.
I'm not surprised my tolerance has gone down as I've got older, I didn't realise it would vanish completely.
