For quite some time I&#x27;d been stressing myself <i>really</i> hard, working way, way too much, and ingesting ridiculous amounts of caffeine to help prop myself up.<p>For example: I&#x27;d work all day at my regular job, during which time I&#x27;d drink maybe 2-4 cups of coffee.  OK, nothing crazy there. But... then I&#x27;d leave work, go to Barnes &amp; Noble or Starbucks, and sit there and work on the startup for 3-5 hours, during which time I&#x27;d routinely drink a 2 or 3 shot latte, drink a can of Red Bull, and eat a pack of two of chocolate covered espresso beans.  And that was my routine 4 out of 5 nights during the week.  Weekends were more of the same... go sit at a coffee shop and work 3 or 4 hours, maybe leave and go eat some real food, and then come back and work a few more hours, and, again, chugging down lattes, Red Bull and espresso beans.<p>In hindsight it was absolutely crazy, and I should have known better.  But we all think we&#x27;re immortal right up until we find ourselves on a gurney being wheeled into the ER.<p>To be fair, there are lots of things that contribute to heart issues, and I can&#x27;t say for <i>sure</i> that caffeine was a factor.  I was overweight and hadn&#x27;t been very active the past year or so, and my diet wasn&#x27;t the best in general.   But still, I&#x27;d encourage anyone who&#x27;s hitting the caffeine as hard as I was, to consider backing off.  It might not kill you, but it almost certainly isn&#x27;t particularly healthy either.
