started training again last couple days after 1 1/2 weeks off, took a break and picked up hours at work.

Either way after coming back Iv'e gone to my gym 5 times now and each time i only get a half hour workout in before feeling extremely nauseous and having to take a seat. Not sure if this is the problem but I haven't had my protein shakes since my break. Could I have low blood sugar? Sorry if this seems like a dumb question only been lifting hard for about 8 months.
