@kaa1 your pen should have "clicks" if you turn it slowly. Each click is 10mcg. It is not marked. Hope you can see what I mean! Try 4 clicks and then move up to 6, or 7. I was never really able to do the full 8.

I did have fatigue but found that getting up and out helped it a lot. It's hard getting over that bump in the morning but it did ease up for me.
