ooh yeah tonsillitis sucks, I got it when I was in Ireland last year, and didn't want to pay for a doctor, so I went with the "ignore it and hope it goes away" approach.
ended up with such swollen glands in my neck it looked like i had swallowed a golf ball, and then i passed out at work...
went to the doctor that day, got antibiotics, and the lovely miracle tablets cured me! hehe
its important to take it easy, keep your fluids up, eat jelly (and low fat/low GI icecream, bulla make a good one that isnt too many calories) and get better!
