None of the things you mentioned would be considered going overboard for any addict in remission in order to protect themselves and the folks around them and prevent a relapse. He is doing the right things.
If he’s having issues or worried i would recommend he get a ‘sponsor’ in a program that he trusts to confide in. A sponsor is someone that has a lot of sobriety/clean time and experience.
I recommend any addict get a sponsor and follow some kind of program at least intrapersonally because there is no reason to do it the hard way with no guidance from experienced peers and professional drug counsellers. Going it alone increases relapse chance greatly.
I have heard that only 5% of the people in recovery stay clean. But it is not impossible.
What the fuck. So this is what they are going to do to the only few safe blue states, just bully the fuck out of each county? Fuuuuuuuuuuuck
