I am usually very careful with my diet but on Friday when eating out with friends i had a small bottle of beer and a Tiramisu for dessert. I was okay for the rest of the day but I paid for it during the night and the next day. Felt jittery, bungged up with mucus, fatigued with a genral hungover type feeling. I seem to do this to myself once in a while and remember for about a month and then forget and do it again. Still I am learning.
