Things aren’t always as they’re reported to be. I wouldn’t be surprised to find that the reason these products “cause” heart attacks and spontaneous abortions is that the people using them aren’t getting enough rest and/or sleep.
My personal feeling about a lot of stimulants has been, use them for the effect, because they’re a treat for that occasion. I for one have a cup of coffee, and keep it limited to that, then, I also limit nighttime caffeine unless I am driving home or doing something where falling asleep would kill me. I try to use things in moderation if you will. Now, I don’t agree with the idea of not having any caffeine at all, but at the same time, I probably would just say that anything taken to excess can be dangerous, even distilled water.
Travis York on “The Doctors” said that he attended to a trucker in the ER room who was claiming his heart was racing. When Travis questioned him, it turns out the trucker had drank in the neighborhood of 15 bottles of that stuff in an effort to keep awake while on a nighttime delivery..........15 bottles!!!
