Dude Im not really. I was on BZD's for 3-4 months max, tobacco for like 1-2 months. I could only drop one dependency at a time. I swear the syrian rue I was taking daily for a bit after trying to detox for a while opened the door for me. Went from 50mg diclazepam daily down to 45, then 40 over a month I guess, before the rue, then I could get by on 20mg all of a sudden, and drop to 0 easily.
Tobacco I substituted with a smoking cessation blend, like, botanical not fake pot. It had happiness tree flowers, Kanna, Ashwagandha tops, mucuna puriens bean (smokers cut), sassafras. I also would throw in cannabis, on its own, for therapeutic effect. Having only been smoking pipe tobacco out of my bong for 2-3 months... can get some gnarly nicotine rushes first hit of the morning. That stage right before you get sick and vomit. Its like nodding out, can't really move and are somewhat immobilized... ahhh that while drunk feels amazing. One of the herbs in my mix contains small amount of nicotine too and helps repair the respiratory system.
