Thanks Mandi. I will talk to my neurologist about connecting with one of the Cornell faculty. Fortunately, I will have very good insurance, and the company will get the medication from the US, or more likely, Switzerland, where it is manufactured. Regarding heat, I'm fortunate that heat doesn't really affect my condition much at all. It's not as hot at Doha where I live, but it is often 100 with 95% humidity in the summer, and it's not a huge deal. Thanks for the lead on Cornell. :-)
