Thanks guys think its possibly detox, eating more than usual cos when I'm drinking I usually barely eat so I think my body is in shock from everything. I'm quite thin and have low bmi for my ages and height so over eating (full tube of milky buttons last night) my body just ain't used to it. Still feeling it this morning it's such a weird feeling. I was super super sick last week when I put down the drink so I don't know if my body is just out of whack.
Keeping strong I know it will get better and I do feel better regardless of feeling abit off.
