Ellis,

Ellis: {My dose is 2 iu per day, and it has been 2 iu per day for
about 9 years... it was 1 iu or 1.5 or 2.0 or 2.5 or 3.0 the first
year... I settled on 2 iu because it fit my budget better than 3.0
iu. Sometimes I have taken 3 iu per day for a few weeks or months,
but my usual dose has been 2 iu per day. I am 5'11.5 or 6'0" tall,
(1.80 mts) and I weigh 165 lbs. - Ellis}
