Caffeine detox and SMART goals

I want to go on a caffeine detox. What I mean by this is get it totally out of my system so that my tolerance goes low and my brain's adenosine receptors goes back to sort of like before I ever drank caffeine. My ultimate goal is to reintroduce caffeine, but at much lower levels and from healthier sources.

I think there's three stages to this goal. There's the weaning off period of getting myself off caffeine. Get off energy drinks, get off coffee and pop. I'll go off the coffee first. Since I dont drink coffee that much I'll just avoid it all together. As for pop, that'll be tougher. The energy drinks I'll leave until later because even though I only drink two of them a day that would be trickier(Kind of hard to wean yourself off something in such potent amounts) Then get rid of the pop. The detox period will be a different goal because I'll have to figure out ways to cope without caffeine as I use it as a tool to help me concentrate and even cope.

A nurse told me about SMART goals when I showed him my blog. Sometimes he can be really helpful. Even though most of the time I'm wasting time here a few staff here and there are helpful. I knew about SMART goals before but never tried them, he told me a little bit about them and told me to go google them. So I did and found some stuff that I can use.

I'm not sure how to go about this goal but I have a few ideas. I could switch the Pepsi Zero to regular Pepsi. Another idea is to just drink less of the Pepsi Zero. Instead of a whole one litre bottle of Pepsi Zero a day I could drink half of the bottle. I could Wean myself off pop over a period of two months. After I'm not drinking any Pepsi Zero I could drink a half bottle of regular Pepsi, and then do the same I did with Pepsi zero. No pop. 

Next would be the energy drinks, which Id do over the same time period. Drink just one energy drink per day for a period of a month and then take away the next one the next month. I may need to ask someone for some advice how to do this but i was thinking about it. 

The caffeine taper and detox would happen over 4 months. The taper of caffeine would be 2 months, the detox would be another two months. I had an idea of drinking green tea, only in the morning once my adenosine system goes back to normal. 

I wanted to be more moderate with my caffeine intake because I figured it's like throwing water on a greese fire for some of my mental health problems even though it doesnt affect me that much. Even though I can sleep fine on caffeine(I can even have a coffee and go to bed) I know it's interfering with my sleep. I already have trouble with sleep because of a medication I'm on.
