I Have a Question

good morning everyone :) i was just wondering if someone put something into your drink would you have any known effects at the time?! just to let everyone no nothing happened and i ended up home safe :) it's just for the amount of drink i had last night to how drunk i felt was unreal .. (can't walk straight drunk!) thinking back i've had double that amount on a night out and been tipsy but not drunk, (i'm one of these people who knows when i've had enough and go onto soft drinks!) it just doesn't seem to make sense ..
