I was recently sent to Sri Lanka to work here for 3 months. I've been a heavy smoker and drinker for many years already. Since I had a surgery on my knee some 3 years ago (from doing Krav Maga), I haven't done any exercise at all. My working hours are from 12 till 9pm - and since this is a religious country, buying alcohol after 9pm is forbidden, and cigarettes are double price - I figured it's a good opportunity to quit the bad habbits and start taking care of my health.
Anyways I found this "90 days of Action" and I feel like this might be just the right thing, but I admit it's a little frightening to just quit smoking/drinking cold turkey and commit to this program. Any tips or advice?
