I'll try to keep this brief and give you the Post‑it version, as the doctors say when you have to deal with a 1,200‑page file.
On October 21, 2024, I stopped using marijuana. I was smoking three grams a day. I was a husk of a man. I was taking pills. Doctors are against cannabis, but cannabis is less harmful than their pills. When I stopped using cannabis, I went crazy for five days. With the pills, I've now been in the psych ward four times and attempted suicide twice.
To get back to your question, I went to the yoga ashram in Val-Morin. I took three instructor courses and spent two and a half months there. From 2011 to 2012, I took basic instructor training, advanced instructor training, and an intensive sadhana, which is a super-intensive practice for instructors.
Yoga isn't popular among veterans because it's difficult and demanding when you're not doing well. Not to mention the optics are off. As my girlfriend says, it seems feminine. Personally, I find that certain yoga positions, such as the locust, require more effort than when I'm deadlifting four plates. It's not feminine, and you have to breathe properly.
Taking pills is much easier. It doesn't require any effort, but yoga isn't magic either.
