Crazy and/or an addict.
Precious was drinking with Johnson, then Taylor, and at the party. I think the Flexeril is a ruse for usage of other narcotics. She may actually have or had a prescription for the muscle relaxer.
BINGO! (addicts are crazy, LOL)
The main side effect of Flexeril mixed with alcohol is dizziness. She wouldn't have needed anything else to put her in the shape she was in. I think she drank a lot and took a larger dose of the Flex than perscribed, and that put her into a falling-down-drunk condition.
