Interesting stuff...my endo looked at me like I'm a crazy man when I told him about this. It wakes me up most nights about 3.30 am and sometimes it's so strong it feels like my chest will burst....other nights it's OK.

I recently had a sleep study (polysomnography test) and true to form, woke at 3.15. The PC tower at the bedside to which I was connected was ticking away slowly and then the 'volcano' started in......I thought the computer was going to blow a fuse....sounded like a geiger counter at Nagasaki.

Should be interesting to see what shows up on the sleep studt report.
I'll keep y'all posted.
