I have absolutely no idea how there are people that exist out there that can drink 6-10 of them a day without spontaneously combusting from tremor induced cellular friction.

A few years ago my doctor put me on beta blockers to try and manage my migraines. My blood pressure was always within healthy limits, usually around 110/70, on the beta blockers it dropped a little bit, but nothing drastic. My heart rate on the other hand?

Resting, it was 41-45 bmp, sitting and fidgeting it was 54-58bpm, and walking around it was 65-73. I'd have to really push hard at the gym to get it to 100 and it would drop back down so suddenly when I stopped I'd often get blue lips when doing cool down stretches.

My fingers and toes were always blue, I had chilblains in the middle of the summer.

When I asked my doctor if I should try Alpha Blockers because they don't effect your heart he said "just drink a can of redbull 3-4 times a day"

So that's what I did.

It wasn't until I changed doctors and she asked me about my tea and coffee habits that it fully dawned on me just how much caffeine I was having.

I completely forgot tea has caffeine, I'd have 5-8 cups a day, plus 3 no-doze pills, 2 red bulls and a ristretto on most work days. On weekends I'd have 3-4 teas, 2-3 red bulls, 2 coffees and a caffeine based pre-workout.

My resting heart rate during all this was about 58bpm....and I slept like a log.

Anyway, my new doctor was horrified and I'm on alpha blockers now. Still no migraines, I've had to cut out everything caffeinated except 3 cups of tea a day, my resting heart rate is 67bpm....but now I have orthostatic hypotension which kinda sucks. Not as bad as taking trucker crack just so my he would remember to beat. I also struggle with intermittent bouts of insomnia now, which is weird.
