My sympathies; it's going to be a long summer for you. I really thought they might just do radiation and tamoxifen; but to be honest, if I were you, chemo would be the way I'd go.
Lay in a store of non-acidic fruit juice (pear, peach, apricot). They're hard to find (at least they were around here), and all Jim kept buying was baby juices; which tasted fine, but were quite expensive in the quantities I drank them. Couldn't stand anything with acid (or caffeine; or iron).
My best wishes and prayers go out for you. The next 6 months will be quite difficult; but I know you'll do fine.
Tattoos optional?
