Did it take a couple of sessions for you to be able to handle one hour in one session?Yes. I'd remember something I had to do or get a great idea and have to pause to write it down. I later realised it was just another trick my mind will use to regain control.
The point of meditation (for me, anyway) is to stop impulsive behaviour. That means everything must wait, even scratching an itch.
Often I feel very stressed and like I'm about to break down due to the boredom. Did you experience this?
Yes. Just yesterday at about the 1 3/4 hour mark I got incredibly stir crazy. I tried breathing myself calm again, but I must have sounded like a marathon runner on the last mile. In the final 10 minutes or so I settled back in.
You just got to ride out those rough patches. The journey is as valuable as the destination.
