Cycle 3 of Velcade Chemo Going Well

I am half way through the third cycle of chemo and the after-effects are continuing to remain low. Interruped sleep is the most annoying. There are nights when I wake up every 20 to 30 minutes and take 15 to 30 minutes to sleep again. Then there are nights where I wake up once and sleep the rest of the night. I catch up with a nap or two the next day and I am fine. It's more annoying than anything else.
