Benzos,Alcohol,Pot and Food.
Benzos I started very young at 13/14 and was my big one that landed me in rehab in my early 20's, they took all the crap away, miss them everyday, still, but I know how easily I can get hooked on them. Been free of them for a decade with only one or two relapses that only lasted a few weeks. Pot I have been on and off for over 20 years now.
But
food and Booze...
If Pot and Benzos didn't stuff my life up so much I would trade the gluttony for them no worries!
