Of course you can't take a pill and have your body recover in one day, it doesn't happen. Imagine you broke your body for several months, and now it needs time to recover.

The impossibility of falling asleep irritates me at least, and probably you too, so I can understand your desire to restore sleep patterns. I had a period when I had to stay up late at work, and then from overexertion I could not fall asleep, I had to take medication. Now I take special supplements for sleep normalization, you can buy them online at https://nanopep.net/products/epitalon-spray/ a wide range of supplements, but what I needed was a complex for the normalization of biorhythm. It helps not only to improve sleep, but also to increase immunity.
