I'm posting so people like me don't overlook it as a possibility. I hope it helps someone.
After years of trouble shooting since adopting Dr. Peat's principles, I'm about certain that the 14-21 grams of gelatin a day was making my sleep worse. I was usually using Now Brand Beef gelatin but I would also use generic store bought in packets at times and heat it to near boiling in coffee or soup (my caffeine intake doesn't change though).
I went through every supplement or drug that I though could be an issue but never considered gelatin. I only recently noticed that I don't get the same drowsy feeling after gelatin that I get after glycine (although I can't say I noticed it was stimulating) and this ended up being one of the last things that I considered because of the glycine content.
And when I think about it, gelatin powder is one of the rare exceptions where Ray Peat supports a very unnatural food product. The facilities that produce gelatin powder look like mini oil refineries.
I only recently noticed that he mentions collagenous soups for himself and not gelatin powder in all the interviews I've heard. So maybe he had changed his opinion on the powder.
