Well, someone who's larger should be able to hold a bit more than someone who is slight of frame. But the does not necessarily hold true for everyone. Some very small people can drink a lot, while others can't have more than a few cups before they fall asleep.

I'm sorry to say that you'd have to find out for yourself. Do be sure to take someone with you, however, to ensure that you don't get yourself sick by overdoing it. Dying after a night of drinking is highly unpleasant.
