boy do i hear ya. i always take as many credits as possible, but last semester's 19 and this semester's 18 did me in. i guess it just depends on the particular balance of classes and work. i think my mono may have actually been a blessing...now instead of being completely stressed out with my 18 credits (all with huge research papers and/or projects at the same time, of course) i have a tiny lil 11 credits! everything is so much easier to do now that i have less piled up. can't afford to ever do this again, but goddamn i'm going to enjoy it, especially once i feel 100% better.
eek
good luck with all your classes!! hang in there!!
