I can agree to it because I experienced it before.
I have 2 reasons before:
1. It's either I can't sleep because I am excited about how to spend my winnings
2. Or I can't sleep because my winnings are not enough and I am still willing to play more, bet more, and expect to grow those winnings.

So, with that belief, we continue betting, and without realizing it, we've already spent our winnings. I have 2 reasons before:

Many gamblers probably experience this, and while it's frustrating to recall, it's sometimes quite enthusiastic to recount to friends.
