Do you ever do, think, or say things at night and regret it when you wake up?

No, not when you’re drunk.

I can’t sleep on a regular basis, and I don’t know if it is the sleep deprivation that does this for me or what. I have always felt like I “do my best thinking” at night. However, sometimes I think too much and when I wake up I ask myself “What was I thinking?!”
I don’t do CRAZY things, it’s just usually writing a letter and regretting it when I wake up.
Or I try to write in my journal when I am feeling like this and I’ll read it the next day and I feel like a different person.
Night time is also when I have my best “pipe dreams”. But I’m not high… I come up with all these ideas that seem perfect, but I can only see the flaws when I wake up.

Am I alone in this.
