Insomnia

How long have you been on it? Could it be from the increased calcium levels in your blood? Online info says 5% of users experience insomnia with terraparatide, and it's a known side effect of anabolics (bone builders) in general. My calcium levels (on Tymlos) shot up at one point and it made me very jittery, with a high heart rate, and after bloodwork, my Dr pulled me off it for a week. And it has increased my pulse rate in my sleep. I can only do 5 clicks (out of 8) because on 6 clicks or above my heart rate will go up to 165 as I sleep, and that's 8-9 hours after injection. My Dr has given her unofficial approval for me to stay at 5 clicks, and I'm still getting amazing results on the lower dose. Do you take magnesium?
I would ask your Dr for a blood test.
Hope you can resolve it to get some rest!
