This happened to my husband one time when we had dried out for a month. Then we got our hands on some Girl Scout Cookies and after the 4th or 5th toke my husband's eyes started to roll around in his head and he passed out for a few seconds and then was just disoriented and shaky for a while. When he slithered to the floor and when he had something solid under him he started to feel better. We were all worried there for a little while but he recovered and no more heeby jeebies after that. But then, we haven't dried out for a month since that time either.
