I'm not too fond of Jack Daniels either. I am a definite lightweight, it doesn't take much to get me completely wasted. The last time I spent all night puking I only had 8 shots of spiced rum, with nothing to eat all day.
I have learned my limit, and I don't drink too much, so I don't throw up anymore. I really hate throwing up. And by 'I limit myself', I mean I have someone (usually Tehaxx) taking alcohol away from me telling me not to drink anymore, lol. I hate drinking until I'm drunk. Then I'm like "GET ME ANOTHER SHOT!"
I have also never blacked out from drinking too much.
