Good for you! With issues you've posted about on this site, the decrease in caffiene shoukd really help you.
No I haven't cut down on caffiene because I rarely drink something with caffiene. I do not drink coffee or sodas but I do enjoy iced tea and Starbucks refreshers occasionally.
My drink of choice is water, plain, with lemon, or fruit infused. I go through cases of water as well as filtered water from my fridge.
Again, good for you to recognize the issue and take action!!
