Caffeine Blues: Wake up to the Hidden Dangers of America's #1 Drug Book

I didn't think I consumed much caffeine until this book opened my eyes to the fact that there is quite a lot of caffeine in tea, not just coffee and other known sources. My many teas a day habit was contributing to my mood swings. I quit tea and coffee cold turkey (in 2006) and boy did I have a headache for a few days. It is recommended that you reduce your intake gradually but I am a bit of an all or nothing girl so just got it over with. It was worth it, I discovered that it's possible to go to bed and just fall asleep - I thought it was normal to toss and turn for a few hours first. I discovered that ones mood can hold steady through the day and doesn't need to plummet down and then be "fixed" up by the next drink of tea or coffee.
I drank various herbal teas for a while when I quit but now I pretty much just drink rooibus (redbush) a naturally caffeine free tea that, to me, tastes sweet without milk or sugar.
