Stop in for a cup of coffee

It may be time for me to cut my dose to 10 mg instead of 20. If I start feeling better then I will know. My numbers shouldn't suffer. My total numbers are in the 140 range on 20mg. I was at 225 forever without taking anything.
Guess the numbering system is different here. I was at 7,which is considered to be dangerously high,now at 4 which is very good.
