Why oh why

Feeling so yucky today... 5w5d & just nearly vommed... For the last week and a half every morning I wake up feeling sickly but have found it's because my blood sugar level is low so I eat something and drink some water and it goes away.. Thought that was the case this morning but I was sadly mistaken when I dry heaved :-( help, I have work in 3 hours :-( ughhhh, tell me I'm not alone on the sickness thing??? ???
