Peach is my favorite by far. Sweet melon was too sweet to me (builds fortress and prepares for attack). I've got an order of cinnamon on hold as well as some earl grey, both are supposed to be good for mixing
If you aren't tolerant of nicotine, be careful. Just take a draw about once a minute. Or you'll end up like me, head down on the desk, getting fragged repeatedly in quake.
Unless you don't play quake.
