I hate to double-post, but I just realised that the Downs is actually more effective in keeping me awake than coffee is. Not that I would know, since I don't drink, and don't intend to learn drinking, coffee.
PS. I also noticed that a good number of the posters in this thread are (was, in the case of
Celuien) Biology -- Biochemistry in the case of
Farael -- majors. Ironic that those who are supposed to be studying life seem to end up having less of it...
