@713j I am at that burden. I have a pacemaker and it should be paced at 98%. It paces at 92% because of the hundreds of thousands of PVCs I get.

What works for me is to get physically tired. I am an exerciser (cleared to do) and find that I am very relaxed from it and helps me relax and go to sleep. I also use reading to tire my brain out and get sleepy. Just pick a good book though so your mind focuses on the book not your PVCs.
