Albert, I was thinking of you this morning and about insomnia. Something I've used with some success--it doesn't work all the time--is progressive relaxation. I'm not sure if you're familiar with that technique, but it may also help you during a panic attack. The idea is start at your toes and first tighten your muscles as much as you can, then release your breath and relax your muscles at the same time. So you start with your toes, then feet, then ankles, then calves... etc. working your way through all your various muscle groups. I'm usually asleep before I get to my arms.
