help with hormones?

[jentx]

Please help if you can. My onc seems suddenly non-committal about next steps and I feel a little lost. I haven't posted here before, but was hoping someone could give me some advice:

My cancer stats: 1.5cm IDC, stage 1, grade 3, no nodes, strongly ER/PR and Her2+++
dx'd 12/07, bilat 1/08, TCH Mar-April, Taxol + Herceptin May, Herceptin until 5/09

I'm currently taking Tamoxifen with only minor SEs, but my estrogen levels remain high and am clearly pre-menopausal.

My questions:

I assume that OS or an ooph is in my immediate future (my estrogen levels are high!). Any advice about the best route? Are any of the OS drugs easier than others?

Tamoxifen or AI? I know many consider Tamoxifen sub-optimal for Her2+, yet many oncs still prefer it. Mine says my age (42) is one good reason to stay on it if I can, if only for a couple of years. If it's a safe and responsible choice, I'd like to, since I feel pretty good on it so far (since end of June). I can also see pretty plainly the high drop out rate on AIs-- the SEs seem to be a quality of life nightmare. But I have a young child and will do whatever I need to to see him grow up.

Thanks in advance for any advice of for sharing your experience.
