People who use Heisig's method literally as described in the book seem to be a minority. I did review keyword -> kanji but stopped writing them out after the first ~100, and switched to kanji -> keyword near the end of RTK3, so didn't really "do Heisig" either.
Added: With approaching 3500 kanji in my reading deck the idea of learning to write them all in order to read them is patently absurd. Yet "write them in order to read them" is Heisig's method in a nutshell.
