Is insomnia a common side effect of Gleevec?
On 400mg doses, I had no issue sleeping whatsoever. In fact, taking 400mg Gleevec before bed seemed to act as a mild sleep aid. Now that I'm trying 800mg doses, it's giving me a really odd version of insomnia every single night. What's happening now is that I fall asleep without issue, and then awaken after 1.5 - 3 hrs and cannot fall back asleep again w/o taking Ambien sleep meds in the middle of the night. I've tried dose splitting without any change in results. I hope this is just a transitional thing, as my body adjusts to the larger doses.
