Ok. Never seen that. The People I know feel faint, sweaty, blurry vision, or just faint. They might get grumpy or be short with people because they feel bad nothing severe.
With this answer I'd say no. If you're diabetic you just faint, instead of getting all crazy and shit. The answer should be found in what happens if your not on meds. We could sedate tigers and put them in a petting zoo, but we don't.
