Even though I have to watch the amount of tea I drink because of iron anemia issues, I buy the decaf teas, and try to stick with green or white tea.
I do enjoy (and I mean ENJOY) my soda with popcorn at the movies; it's all part of the experience. I drink the new Zero Coke which doesn't have the metallic aftertaste that diet drinks do. I don't like the chemicals, but since it's rarely more than once a week, I will live (I hope) with that. I still stir the soda, to get rid of the carbonation. When I take it home (free refill) I leave it open in the frig to go totally flat!
When I have difficult breathing, I drink hot coffee. Not only does the hot liquid help open up the airway, but the caffeine does too. Caffeine is a drug and if you use that way, do it smartly. I will also "use" it to try and help curb a migraine while the migraine med kicks in... caffeine constricts the blood vessels, and migraines operate on the wide open vessels to the brain creating "too much" blood flow.
How is everyone doing on curbing their caffeine? I think it's great that you are working on this!
