Yeah, I’m episodic and mine always start off sort of low key. They usually ramp up in frequency and amplitude until I’m going full tilt, 4-6 hits a night at peak. Although I’m not as clockwork regular as some. I’ve even had a few low level hits and then not gone into cycle. Like a miss or something. But usually when I start feeling pain on my right side, I get my stuff ready to rock. Better safe than sorry. I got caught out of oxygen once when a cycle started going, thinking maybe I’d miss, and I paid the Piper. One time of that was enough, I’m not doing a repeat of that debacle. So I concur with the seasoned veterans above. Time to get your stuff sorted. Better safe than sorry, and all that.
