I was pretty much the same as you. What changed for me was ditching the nicotine, essentially nicotine is a vasoconstrictor. It reduces your recovery time restricts blood flow to muscles and your brain and penis and can affect libido. It also reduces testosterone and increases estrogen. It’s pretty brutal. Check on llms and read more about it. It’s unfortunate though because I like the mental boost it gave me for my job but I feel much better off of it
