Forteo side effects high calcium decreasing dosage to every other day

Hello, I started Forteo 8 months ago, with what appeared to be no side effects. Then, about 6 months in, I started feeling terrible. Extreme fatigue, join pain, brain fog, nausea, just generally feeling very unwell. a month ago, my blood calcium was 10.8 which is considered "moderately elevated." My symptoms continued to worsen. Another blood test of calcium showed still elevated. I stopped taking it for 3 nights, then doc said to take every other night. The first night that I didn't take it I felt SOOO much better the next morning. So I will do the every other night and see what happens. I think the issue is that I am small -- 5'2" and 100 lb. (I lost 5 lb from the nausea and loss of appetite) -- I just can't fathom that I should be on the same dose as a 200lb woman. Are there other lightweights out there who have had a similar issue? Thanks!
