Finally managed to get Bryce as well.
The trick is to be reluctant about drinking so that when you finally do agree to humor him, you're doing it only for his sake.
The rest should be pretty common sense, just pick whatever choice that produces the best immediate reaction, and if you have only negative things to say, choose to say nothing instead.
Make sure that when you're drunk on the ground, you concede rather than pushing it too far. If you did so, afterwards you will end up arguing about it, whereas conceding will instead cause him to apologize at the end for pushing you to drink.
The good outcome is him inviting you over next time to see what other activities you can do together to see who has better "endurance".
