Hey again Linda,
May I make a suggestion if you and Al do enter the clinical trial? Everyone who enters the grounds of NIH goes through a very thorough security check. Your person, any bags you are carrying, and everything in your car. Sometimes the cars can be lined up. Since being in the trial entails frequent visits to NIH I would suggest your asking for a permanent pass so all you have to do is show it and by-pass the security check. It is invaluable. They are good for a year at a time.
Again, best of luck and God Bless. Keep us posted. And if you have any questions that I can help you with please feel free to contact me - either through the forums or my e-mail -
