Hi @justme34, each click is 10 mcg. To test it, you can click thru to 8 clicks, then just twist it back to 0. Sometimes I lose count, but back it up to 0, and start counting clicks again. I got very sick for 2 days when I tried the full 8 clicks originally, so i restarted at 1 click for 2-3 days, then 2 clicks for 2-3 days, etc. I've been on it 11 months, but can't really get higher than 5 clicks, and my Dr said that's okay to stay at for now. I've had great results on it, so give your body time to adapt. Drink lots of liquid when you inject. I switched to afternoon injections so I don't have to get up to pee.
