Hi RW -- Mexico was great! It was nice to check out of reality and be away from phones, email, internet, students, and MS! What's the lidocaine pop?? You know, I got a couple of sore throats the first 2 infusions also. Weird, huh? For some reason today I'm feeling pretty good--not many side effects from the Ty. It's so hit or miss sometimes and I have no idea why.
