I also believe that 72 hours is key to defeating an addiction in general. I was also terribly addicted to soft drinks, and I had known that I wanted to give them up entirely for some time. But how? I got to have that tasty, fizzy drink mmm. I loved soft drinks so much that, apparently, I used to drink 2 liters of it per day.
This caught up with me eventually, and I became a diabetic, the first ever in my family. Before I got that condition under control, I landed in the ICU with a real serious episode of hyperglycemia. It was during this time that I realized dietary changes must be made, including soft drinks, or I will die.
I remember speaking with the diabetic advisor one day, I said to her that I had been able to quit a number of things in my life so far, but soft drinks worried me, even more than cigarettes did. She said to me how long have you been here in the ICU, I said four days. She asked me how are you feeling without your soda, it's been four days without any, are you anxious?
I said no, and I knew right then that I was done with soft drinks forever. That was about five months ago now, and still not a single soft drink. I think that the same principle can also apply to nicotine addiction. If one can just go a short X amount of time without the substance in question and realize that the stories of withdrawl may be far fetched afterall.
What I learned in the three days that I initially quit smoking cigs and the four days that I didn't drink any soft drinks due to being in the hospital is that there was no addiction. It was just something that I had imagained in my mind and believed was real, but all I had to do was turn around and walk away.
Honestly, I'm heading down the same path. I drink 4-5 cans a day, and I feel them taking a toll on me. Not only do I feel it, but you can obviously see it. My Dad was diagnosed with diabetes back around 2003 or so, and when I had a physical with the doctor in 2009, he said that I was almost guaranteed to get it unless I changed my habits. It's so terribly hard, honestly.
Do you mind me asking, how old are you? I'm 27, and he said that I'd have diabetes by 30, if I didn't make a change.
The biggest problem I have is headaches. I mean, it really sounds like a pathetic excuse, but when you're reliant on caffeine and don't have it, you get massive headaches. I'm sure you've been in my shoes.
