The way I see it, "You made your bed, now lie in it," means you set in motion the events that led to your trouble, and now you must pay the consequences."
Add an "if" to it and you get the Polish meaning ("if you set in motion the events that led to your trouble, you must pay the consequences." because "if you made the bed badly, you won't be well rested next morning"). Noone uses that saying when anything good comes, I am probably the only one seeing the possible positive explanation bacause I care enough to interpret the sayings and wonder where it comes from and what sense it makes, not just remember the meaning.
BTW. We have a similar one "Nawarzyłeś piwa więc teraz je wypij"(You made a lot of beer, so drink it now), meaning the same thing: your actions have (bad) consequences so now you have to deal with them. (My understanding - I don't make or drink beer but when I was practicing cooking I often cooked too much stuff noone wanted to eat so I had to eat it in order not to waste food - it's just like this. I could always throw it out though if it was really bad, so who cares? Also - probably someone liking beer would be happy drinking all the beer but I guess there is an amount of beer noone is able to drink before it goes bad even if they love it.)
