I don’t doubt it may work for some people (placebo maybe?) but not for me. I have sinusitis, I was told that I may breathe well with acupuncture. Five sessions later, zero improvement, and a lot of money spent. The guy told me that I may need 5 more sessions because somehow my body was not reacting as expected…. For free? No, paying again. No, thanks.
That’s an incredibly naive answer.
About the peeing at night, a doctor I saw in TV said that if during the day you don’t go immediately to pee when you feel the need but when you REALLY need to, then it’s easier to stay sleeping at night. He explained how there are 2 mechanisms to control pee: the bladder (I think that’s the word in English?) and the brain. And that quite often we train the brain to go to pee before it’s phisically needed.
