I don’t know if it’s the same issue, but this happened to me. Some of the E.R. docs were baffled, but one had the answer. I was suffering rapid atrial fibrillations due to what they call “holiday heart.” Basically it happens when you’re dehydrated, which is common when you go all out getting drunk like I was doing. Most people, however, are not susceptible to it. It causes no permanent damage.
The feeling lasted for several days and I got it about half a dozen times over the next few months after that, again, always lasting several days. For those, though, I did not go to the hospital since I knew what the problem was and that it would pass if I waited long enough. I quit drinking last September and it hasn’t happened since.
Please oh please oh PLEASE get another opinion!! My best friend had issues like what you are describing (although he only smokes pot and drinks; none of the heavier stuff) and at several points thought he must have been having a heart attack. The episodes increased in frequency and intensity, and the ER docs couldn’t seem to figure out what his problem was. They put him on anxiety meds, and took him off his ADHD meds, but it didn’t help him at all. At last, a different doctor looked at him, and requested a CT Scan and an MRI, and discovered that my friend had a heart defect that, when his blood pressure rose (due to stress or anxiety) caused the blood in his heart to just circle around, instead of pumping out into his body. Untreated, it would have proven fatal. Thankfully, there’s a surgery that took care of it and he’s fine now.
While I’m (mostly) sure that your chances of sharing this condition are slim to none, it’s worth a shot. Get checked out, please. Oh, and if you’re gonna do drugs, stick with the natural stuff. But drugs are bad, m’kay?
Given your responses since the thread was moved, my judgement is that you are seeking medical advice, and I strongly urge you to do so from a qualified professional.
On an unrelated note, I’d like to remind new member telecommunications that the guiding rule on this message board is, “Don’t be a jerk.”
