It may be a mixture of ketosis and the fact that my body has gone into shock through not having any alcohol for a week LOL! When I sat back and thought about it I realised that I have been having at least one glass of wine most nights (if not every night) for the last 12-18 months, quite frightening when you realise. So, without saying I am an alkie it honestly could be a bit of withdrawal symptons on that part
