@2connie, I was on a half dose of Tymlos for 10 months. I couldn't tolerate any more. I switched to Forteo and have been on that for 2 months with barely any side effects. It is so nice not to feel dizzy and nauseous like I felt on Tymlos. The only significant problem I had with Forteo, like Tymlos, was frequent urination at night after taking the medication. I recently switched to taking my Forteo after dinner, so the urination happens while I'm awake. Now I'm getting a better night's sleep!
