Transitioning out of swaddle

For those of you, ladies, who already transitioned your babies out of swaddle and just went straight to sleep sack, how many sleepless nights did you have?

I want to start the process, but I’m dreading the sleepless nights that will come with it, and I think it would help to get an idea how quickly babies adjust.

I’ve tried a few transitional products ( Merlin magic suit and zippady zip) , and baby slept horrible in them, so I think I should just go cold turkey and switch her to sleep sack (nested bean)
