hi paul,
Im about to bore you with my solution to your fidgetyness, I too have been on high doses of steroids and many moons ago i attended a ten day intensive course of meditation.
the course stipulated, no talking, no eye contact and ten hours per day were spent sitting trying to achieve the instruction.
For the first three days we were asked to simply observe our breathing, concentrating on the air entering your nose and the air leaving, without trying to change or force its natural flow.
You will find at first this observation is impossible to maintain for more than a few seconds, your mind will disappear to a new thought almost immediately, if you keep on returning your mind to the air passing in and out you'll notice that as the air goes in, it will be ever so slightly warmer as it comes out and if you really study hard you can feel the hairs in your nose moving in and out. Now, although i had the opportunity to attend this intensive instruction, it did take me the full three days to master some degree of control over my wandering thoughts the course then started several new observations but this first technique of controlling your thoughts helps me no end, especially when lying awake with hyper tension and i now find as i slowly calm my mind, sleep usually follows.
You will probably try to do this a couple of times and think that its not for you, but ask yourself, when we close our eyes shouldn't we be able to control our minds, if you slow your thoughts your body will usually follow.
