Having swapped over to DDG a couple years back, I recall my frustration and Google-fallback habit lasting for ~6mo. At this point I'll end up using the big G maybe every week or two--mostly I forget that they're there.
Honestly, my second most-used "search" style interface these days is Wolfram Alpha. Google comes in _third._
Say what you will about their respective search result quality, I found that a lot of the delta between DDG and G! could be made up by just spending time with DDG. I believe I've subconsciously adjusted both my keyword structure (I'm conscious of using "explicitly" "quoted" "keywords" to ensure they're included in my results) and my expectations.
