Issues with insomnia for a while.worse on tamoxifen.ambien (zolpidem) does not work for me.would i upset or step on my oncologists toes if i went to a sleep spec?

Absolutely not: I am sure the oncologist would very much appreciate the input from the sleep specialist. Your oncologist knows the effect of sleep and fatigue on the immune system and the importance of a good nights sleep. Consultation would be most welcome I am sure. Best wishes.

I dont think so: You could even ask the oncologist if they feel it is a good idea...
