gosh... it's been awhile... i can tell ya that i probably personally wouldn't have started that late in the afternoon... hopefully you're looking to be up late tonite
as for the dosage.. i think you follow a standard dosage pattern, does the bottle list the conversions? maybe invest in one of those eyedropper type things that'll help you measure it (like the kind they use to give babies medicine with ?
what's it taste like? for some reason i keep envisoning grape??
