Well there are a few possibilities:
-pills: sublingual intake of bioidentical micronized estrogen... Spreading the daily dose in a few small doses instead of two big ones might help keep levels more steady, instead of highs and lows, which might affect mood in a pms like way...
some people use very small doses of aspirin additionally against clotting... you might ask your doc...
and avoiding smoking should help...
-patches: the vivelle patches are said to be small and stick well.
Skins are different so reaction is individual. One possibility is to combine one patch with pills. The patch to keep levels steady.
-gels: quite convenient with intake
-injections: with biweekly injections there might be a low after 10 days. With weekly injections levels are more steady.
-implants: steady levels and no hassle.

Its a well known effect considered safe only with implants and injections.
You might look up postings of Jennygirl, she had very good results with implants without anti androgens.
Bioidentical progesterone might compliment estrogen.
It might help with mood, with breast development, even out some side effects of estrogen and has some anti androgen effects.
