Healthygoals - out of interest did you have much sugar last night ? I have very little in my diet at all and completely cut it out occasionally for two weeks then slowly introduce natural sugars back in, however a few nights ago I had a real craving and ate a few sweets & chocolates after having a dessert as well earlier in the evening - following morning I felt the same like I'd been out on the ale - just a thought that maybe too much sugar made you feel rough.
