Hi, Check out the other threads on Evenity and you will find quite a bit of information. I never experienced the fatigue, brain fog or amxiety issues but did have quite debilitating joint pain which began after the 6-7 months of treatment. Completed 11 mos and couldn't take not being able to move without pain in muscles and joints-hips were the worst but every joint right down to my fingers to one extent or another. Hope all goes well and the information on these threads are very helpful. You know "you" best so don't discount how you are feeling.
