The past few months I have had a horrible time sleeping, suffering from mental fogginess, and have been dealing with unnecessary anxiety and mood problems. I started to realize that perhaps I am sensitive to caffeine and that this may be the culprit to these issues. Not only that, caffeine is known to cause dehydration and heart problems, so to me, the health benefits that some scientists claim are not significant compared to its detrimental effects. Instead, I have decided to incorporate more exercise in my life and eat a healthier diet, so as perhaps to keep my energy levels going throughout the day. Caffeine is a drug, and it is very addicting. Not only that, there are days where I am sure at least half of my calories consumed were on sugary caffeinated beverages. I also have wasted quite a bit of money on this bad habit.
