I have, and have been gargling salt water as well. It's improved since Wednesday, but still hurts to the point that I think twice about eating or drinking.
I always hated when i told people that I WAS gargling with the stupid salt water. And then to hear, it's not enough. When I was diagnosed with Tonsilitis, which came right back after antibiotics killed the first bout, the doc told me that 10-15 times a day was key and it keeps inflamation down. But that seems like soo much work when you're sick! Try teas, too.
