Headaches! Help :(

I've not yet finished my first month on Tamoxifen and am already considering stopping it.

Since I started it, I've been unable to sleep without taking tons of things to help (klonopin, melatonin, & muscle relaxers at the same time), and even then I wake after a few hours. This has been killing me but I decided I would try changing my dosage timing and wait and see if it improved with time.

Now, though, I've started getting horrible headaches. They never really go away, but they are in the background in the morning and worsen later on. I can take Fioricet AND 800 mg ibuprofen AND Excedrin Migraine AND a muscle relaxer and only experience 50% relief. Always on the right side, always behind the eye. My eye hurts to move and when I press on it. The headaches are severe as migraines, but feel different.

I can't take it anymore. It has been going on for 1.5 weeks, with only ONE morning where I was without a headache in all that time.

I talked to GP about it and he recommended the Fioricet. Plastic surgeon told me to talk to MO, but I don't see her again for a few months and am now wondering if there is even a point. Obviously, the headaches can't be helped with the medications I've been using, and I can't take something like percocet and work/drive.

Anyone here have headaches that went away after a period of time or found a trick that helped (timing, herb, anything at all)?

Also, if you have any sleeping tips, I'd love to hear those also
