Stress levels in general are higher in the morning and the more stressed out you are the more sensitive you get to things that cause palpitations... I've had all the trigger conditions you describe here except for the poking a certain spot one. The worrying that it will never stop just makes it worse and worse. It took focusing on the fact that it will eventually stop to get me over it.

When it was at its worst I would have fits of bigeminy/trigeminy lasting for a minute or two at a time, with lots of scattered single ectopics in between. To convince myself it wouldn't hurt me I took up the habit of taking long relaxing walks in the countryside with my mp3 player in the morning, just to prove that I wouldn't drop dead from the exercise. At first it was pretty much guaranteed I would get lots and lots of ectopics when I started, but after about 5 minutes of walking they would taper off and then stop altogether.

I started to look forward to facing the fear each day just to break through to the other side... it was a wonderful feeling! Gradually the palps started to come less and less often, as if they'd sensed their defeat. Facing them for a few minutes in a day knowing they'd pass turned into facing that I had them for a day, or several days, knowing that they wouldn't last forever.

Now I still get them, normally less in one day than I can count on a hand, but they don't bother me. Sometimes I have rough bouts when I am under a lot of stress and/or suffer a panic attack (I have a MVP which I understand makes me prone to them)... these rough spots may last a day or three but I just remind myself that if I weather them out, they go away... and they do. The main thing is I don't let them bother me when they are here. I beat them with faith and endurance.

I hope this helps you find your own solution. This thing is like a monster that feeds on your fear, growing stronger... the more you worry and monitor and check, the more sensitive you become to things that trigger the palps, and the more you will have of them. Deny it the fear it feeds on, and it will shrivel up to the tiny insignificant thing it really is.

My thoughts and prayers with you until that time!
