As a recovering pop junkie I have some advice.
DO NOT try & quit cold turkey! You will get massive withdrawal headaches & may even get sick.
There r several approaches that u could try.
If u have good will power u can try & limit yourself to a certain amount of pop a day (tell yourself u r going to have ''x'' number of cans a day). Say u r going to have 4 cans a day for one week. Then, the next week try 3 a day, then the next week try 2 a day, then the next week try 1 a day, & then slowly start spacing the interval out on the 1 a day into 1 every 2 days, 1 every 3 days, etc. This can take some time, but it SLOWLY weans it out of ur system.
Another method involves the diet version of ur drink of choice. Say u r drinking regular Dr. Pepper.Try mixing Diet Dr. Pepper into ur regular Dr. Pepper slowly. Start by pouring 3/4 of a glass of Dr. Pepper & adding 1/4 a glass of Diet Dr. Pepper. Eventually over a few weeks, u will end up replacing the Dr. Pepper with Diet Dr. Pepper. While, the diet versions of soda r really not that much better than the regular versions, u can still get ur ''soda fix''.
Yet another method involves diluting ur favorite soda over time with water. Much like the Regular/Diet method, u will end up completely diluting ur regular soda with water. Water is much healthier than soda & will be a good choice.
Finally, do not cut soda/energy drinks out of ur system completely, it will be very hard. Right now, I can go a whole week without a soda. Because of that, I ''reward'' myself once a week with a Dr. Pepper or Coke. I do not crave the soda as much, & I do not get the headaches either.
