I have been on Tasigna for about 2 1/2 weeks now, and I am finding that I am having trouble sleeping. When I first started Tasigna, I had a rash and a really itchy scalp. The rash and scalp itch have mostly subsided, aside from some dry skin. However, I am finding it very hard to sleep sometimes. My onc said that sleeping issues are common. I understand that everybody is different, and that side effects vary individual to individual. I was on 800mg of Gleevec and the only side effects I had were a mild skin irritation and some nausea if I didn't eat enough when I took it, but I became resistant. I noticed that some people have experienced fatigue on Tasigna and I have too, but it seems coupled with the inability to sleep once and while. Just wondering if anybody else experiences this, and or if it will pass as my body gets used to metabolizing Tasigna.
