I've been feeling generally rubbish for over a month now - tired easily, headaches, nausea, slightly upset tummy and what can only be described as a hangover feeling which is either there all day or comes on about lunchtime and doesn't really shift for the rest of the day! I'm not drinking hardly any alcohol at all . I seem to need to drink lots of sugary drinks or eat to feel any better.
Went to GP who wanted to do a fasting blood test which showed everything normal except elevated liver enzymes (AST). Anyone had anything similar?
