It took me a long time to be able to speak English as well as I do now.
「今くらい英語を話せるようになるまで、すごく時間がかかった」
二つ表現してみました。
今話してるように like the way I do now
原形比較級を使って、as well as I do now
～するのに長い時間がかかる it takes me a long time to ~
不定詞 to の後に助動詞 can は使えないので、be able to ~
It took me a long time to be able to speak English like the way I do now.
