So I’ve dealt with these god awful attacks for more than twenty years now and they normally last between 3 and 6 weeks. I used to deal with them with no assistance, just suffered through. Then, I found oxygen through the help of you wonderful folks. While not perfect - I travel extensively for work - one hell of a lot better than powering through while wishing for my own demise. This summer my doc put me on Verapamil. It worked great to take the edge off and reduce the frequency of the attacks but now I seem to have a problem. I had that “feeling” I get at the end of a period where I figured it was all done after 5 weeks. I stopped taking the pills and the attack not only came back but came back way worse. I typically have very few attacks during the day but now I’m having them constantly. If I close my eyes and nod off I sleep for 15 minutes and I’m back on the air. This SUCKS!!!! So, anyone ever have this experience with Verapamil? Anyone ever hear of someone going from episodic to chronic? I’ll really be hating life if I can’t get some sleep soon. I haven’t slept more than 2 hours in the last three days. Thanks in advance for any info anyone has…
