Kerri,
I don't know the correct medical answer to that, but it is important to get rid of your headache, too & if ibuprofen is the ticket, why not? You aren't having surgery, where blood thinning would really be an issue. You're having the shorter chemos I think. They are somewhat easier to bounce back from.

I suppose/hope you don't have your headache anymore. Yes, I too would get to a situation where I did not know if I could take this, or eat that, or whatever, and then would try to remember to ask. Write it down, make a running list of questions as they come up. You'll get through this. I felt like a light weight going through all that radiation/chemo stuff, but you know what, it didn't matter, cause like you, I'm tough.
