This question already has an answer here:

I once heard that you cannot wake up in the morning being fleishig, meaning if you go to sleep for the night, even if you sleep less than 6 hours (or whatever time you wait), you are pareve and can eat milchigs when you wake up.

What is the source for this and what is the reasoning?

    Could you add "Is this true?" to your set of questions? It sounds dubious to me. – Isaac Moses Oct 2 '14 at 20:56
  • @IsaacMoses I could, but I heard it from a Talmud chochom. Do I need to add that? I don't doubt that there is such an opinion. – jim Oct 2 '14 at 20:57
  • @IsaacMoses, I've seen the opinion in print (now I have to remember the name of the sefer but it was of 20th century vintage). Whether or not is the halacha is a different question, but I can attest that it does exist as well. – Yishai Oct 2 '14 at 20:58

I've heard this from unlearned people only. I assume they are mixing themselves up with keilim. That is, in the idea of nosein taam lifgam, we say the blios in a kli become no longer considered halachicaly viable, bidieved at least, after being in the kli over night or over a 24 hour period. The popular opinion is to hold 24 hours but the other opinion held simply passing of the night counts. I think this is where the mistake you mention comes from.

  • What's the evidence for overnight being sufficient for nosein taam lifgam? – Avrohom Yitzchok Oct 2 '14 at 21:04

    @Avrohom Yitzchok what do you mean evidence? Its a shita in the rishonim just like 24 hrs. In fact its not so nidcha from halacha in the achronim, I just don't have the time to check up what I would say off the cuff so I'm not going to. – user6591 Oct 2 '14 at 21:15
