I have been drinking soda like it's water for about 10 years now.

About a year later I was first diagnosed with mental illness. Ever since then I have been tired all the time. If I don't drink something with caffeine in it throughout the day I literally fall asleep sitting up. I just can't stay awake.

Over the past year I have gained between 50-60 pounds. I want to start trying to lose weight and I think one of the first steps is to clean up my diet, which includes removing soda.

I have tried quitting soda before but I ended up drinking things that had close to as many calories as the soda because I don't like the taste of water. I know I have to stop gradually if I don't want to suffer severe headaches. I get migraines so the one time I tried stopping cold turkey I had a migraine for two weeks straight.

I know how to go about quitting it for the most part, but I am worried about the fatigue that will come from a lack of caffeine. Any advice on helping with the energy slump from lack of soda would be amazing
