@doorman- I believe I started with a half of mg. initially and was bumped up to 1 mg. within the 1st year.
You may be right about the responders. It seemed to take a month or more before I could really realze the differences which was a huge relief!
I've never had the urge to increase from 1 mg. I still bring along an extra half in a plastic bag when I travel especially on airplanes. It seems knowing I have some extra with me helps any anxiety and I can't ever remember needing to take it. Jim@thankful
