Yeah its a whole lot of caffeine. For those who suffer from insomnia or who have heart problems I've recommended in the past to see your doctor first. Caffeine doesn't bother me at all. I could drink tea or coffee all day and still snore thru the night. For those that want to try it but don't want as much caffeine, try 2 cups per day 1 tea bag per cup or whatever way is best for you. Try the decaf black tea, Tetley's brand and see if that works for you also. I did research on black tea and I was impressed that it said black tea has the ability to eliminate strong Body Odor s, foot odors, and bad breath. Helpmylifeisover, your life is not over. Try the black tea thing for 2 weeks and see how those terrible odors disappear. Tetley's Premium British Blend black tea is the best. And guess what it might not take that long!....Also, just a suggestion: Switch up on your probiotics to another brand because your body will adapt or get use to that particular brand and stop being as effective. I strongly suggest Dannon's Activia yogurt (I like vanilla, peach, strawberry are my favorites)...If, and when the black tea stops working I will switch to another brand, however me and the black tea are "on a roll". 4 months and counting with no abnormal odors from my TMAU as long as I regularly drink my black tea.....take care and keep me posted.
