Ok I'm on a mission to diagnose myself because i've found that doctors are of no use to me and don't have the time to diagnose something that isn't completely obvious too them (In my experience anyway)

Ok the symptoms i'll give you are symtoms i have throughout most of everyday but are a lot worse when i drink a considerable amount of tea/coffee and alcohol. Possibly when i eat also.

Pale skin
glazed/bloodshot and tired looking eyes
puffy bloated face (worse in the morning)
shaky hands
pulsating/pounding heart morning after drinking alcohol
frequent urination
Become introverted and irritable because of general feelings of sluggishness
clouded thinking
Can sleep 12-15 hours when uninterupted

Let me know if you think these symtoms relate to Hypoglycemia.
