I'd try a sequential HRT regime - you do have to put up with monthly bleeds though. With continuous HRT, progesterone is taken continouously and can give more side effects.
Look under TREATMENTS on this site to see the options.
Why not try Oestrogel (applied every day to inner thighs) with Provera separately as Pills. Start with a sequi regime to see if the progesterone suits.
