<human>: Could you distill the essence of the text into 1-3 sentences?

I've had high blood pressure for two years now. Recently my meds got shifted because the first one wasn't doing the job. So my cardiologist switched me to metoprolol and man does that do the trick. I went from 140/100 to 110/75. All is well. Minus one little caveat. See, there is a warning on the bottle "take with or immediately after food" There is a very, very good reason for that warning as I found out. 

So, I get up in the morning and, under normal circumstance, I'll grab breaksfast, cereal, poptarts, something. This morning I go to grab breakfast and we are out of anything I can just grab and eat and since I'm half awake and lazy I decide I'll just skip breakfast for now and grab something hwen I headed out in an hour or two. So I sit down at my computer and take my morning pills, including my new blood pressure meds. Friends and neighbors, neighbors and friends, there is a very, VERY good reason that warning is on that bottle. Not 15 minutes after taking my meds I start to get a little heartburn. I dismiss it as having skipped breakfast and keep going about my morning routine. We'll call that FU number two. 

Not 15 minutes after that the "little heartburn" escalates into "it feels like I got horse kicked by a Clydesdale" levels of heartburn. I mean, curled into a ball and weeping in a corner levels of pain. Not the worst pain I've ever been in, but decided in the top 10, if not the top 5. It took roughly an hour for the sensation to back off and it left me shaken and wrung out. I'm trying to figure out if I need to run to the doctor because maybe I have a stomach ulcer or something else serious and right about then I remember that warning label "take with or directly after food" A quick google search later and I find out *why* that warning is there: a common side effect is serious heartburn. Oh. Damn.
<bot>: be careful with your meds and pay real close attention to any warnings they might have, even if they seem irrelevant. Sometimes the silliest seeming precaution might have a very valid reason behind it, like the devil's own heartburn.
