Needed to lose 3kg (preferably 5kg) to donate a kidney. Had loads of tests and of of the things they found was the onset of "non-alcohol fatty liver", and they recommended cutting down. So just stopped, didnt want anything to get in the way of doing it. All systems go now, they're happy with everything now.
What a cracking bloke you are, not sure if people realise ... ... to be fair I didn't at first. Anyone lucky to know you is blessed imo.
