Mooooooooooo

It is now May and I promised myself that in May I would get off dairy again. The lactose intolerant in me is a loser as I just like cheese too much. Day one going well so far though, few days until the cravings and grumpiness kick in. Drinking a lovely black iced coffee - on a side note is there any scientific reason why I like my cold coffee with no sugar but my hot coffee with?
