Well...I don't know about the activities you suggest for three days.
Anyways, I don't smoke tobacco except for an occasional shisha but rarely and I don't care much for it. I meant that I've been trying to quit my "bad" "habits" by opting for legal natural plants like lactuca virosa, blue lotus, damiana and california poppies.
Which is probably still bad.
Addictions are not healed, they are replaced. Sexual activity and physical exercise increase dopamine release into the brain, and should nullify the irritability. Shisha is typically jam packed with sucrose, though the water in the bong does filter some. Regardless, the first step to leaving any addiction is wanting to leave it, and the second is to be thankful for what it taught. Regretting what you do as you do it is a powerful stress, and besides ulcers, is the pure path to brain cancer. I don't believe spirituality is a topic of interest in this forum, but I'll leave it at self-loathing does not work well when it pairs up with what addiction is.
Try working out then, and then you can find a wife (and apparently, also wash single girls too in a super awesome bath with running water- I was never clear on if you had to be married first...). I recommend pull-ups, and standing on your hands against a wall and pushing up and down for fast exhaustion, then move your arm in circles and do neck exercises (lie flat down, lift your head and shake it "no" back and forth). Of course start with cardio (5-20min x3), but try to do something without social contact with people you're not going to sleep with, at least for me last time I tried I broke a wooden deck and a nose...
I think it's unwise to smoke poppies, and I don't suppose blue lotus shouldn't be for much else then bees and their honey. The rest I have not studied, or can't recall at 6am.
