Thank you!

Very interesting! I'd like to read the rest, too.

I'm not sure that sites like that look that way because they just don't know any better. I think they may be signaling they're not an 'establishment' site, and so *increase* their trustworthiness in the eyes of their target audience.

I took 10 lessons, and I think I could probably have done it with 8. I still feel myself sagging now and again, and then I have to correct myself (and then I wonder why I sagged to begin with, because the correct posture is actually more comfortable). I have also bought a new chair ( https://www.ikea.com/nl/nl/p/kullaberg-bureaustoel-zwart-90325518/, only mine has a different color) and removed the backrest. I have found that chairs with a backrest and armrests tempt you to lean on them, and then you can end up sitting in a wrong posture for a long time without noticing. Without them, I soon notice and can correct myself.

Yes, and I had tried several times before, without success. The difference is that earlier I just wanted to stop smoking for health reasons, but I still loved smoking. After reading the book, I don't want to smoke because I just don't like it anymore.

I'm missing Allen Carr's book (https://www.amazon.com/Allen-Carrs-Easy-Control-Alcohol-ebook/dp/B07B7QRWTH ) in the list of books. I quit drinking after reading that book over 3 years ago, and it was almost like flipping a switch, so fast did it turn off my desire to drink.
