This is my 'slant' on IBT after a week.
Method: I piled 2 x 6's of spare cedar boards 3 high under the top support of a platform frame for a futon bed. This gave me 5" of lift (2 x 6's are not quite 2's). The top leg of the frame allowed for an overhang of a foot or more. Thus, the lift should be about 6" if measured at the head and should produce the desired slope of 5 degrees. I confirmed this with my iPhone (yes, there is an ap for that) which showed a slope of 6 degrees measured in 3 places. I calculated a slope of 4.8 degrees, however, with actual measurements. I found it reassuring to verify the slope with some actual measurements because not all beds have the top legs right under the top part of the mattress. And I'd hate to be a few degrees short of a cure

(I know it doesn't have to be that precise).
Here is a useful link to help with the calculation for those of us who have forgotten our high school trigonometry but wish to be precise.

Initial impressions: I had no difficulty adapting to my new tilted sleep world. I'd venture as far as to say that it was intuitively correct. Indeed, flat beds seem to be an odd idea to me now. I guess Andrew will go down in history as the man who dared to ask, why are beds flat?
My first few nights were a disaster. I immediately came down with a really bad sore throat and fever that laid me up for two days over the holidays. I can't see how it is related except that I rarely get sick. I've, knock on wood, only missed two days of plus full time work in over 20 years due to sickness. I recovered quickly though - enough to put in a 16 hour day on my first day back

.
Apart from that, I have to endorse the positive effects IBT has on posture. I feel much more straight during the day and my upper back scapular muscle pain with which I have always been plagued (non-MS related) has vastly improved. My lower back spine-related pain has increased, however. I'm not relating this to the IBT however, but to having lifted heavy newspapers to take out to the recycling bin over the holidays. I like to use an inverter board occasionally for my back. IBT does seem to stretch your back. You'll be able to maintain your height longer I think.
I am sleeping well and feeling refreshed for most of the day, even though I have been sleeping on 6 hours for most of the week. 7 is ideal for me. I need to work on that (i.e. not go to bed so late). Overall, there is a noticeable, but not dramatic, improvement in my sleep quality and effectiveness since going on IBT.
I think its worth going on IBT for these benefits alone (improved sleep and better posture) outside of any MS therapy.
Abatement of MS symptoms: Thus far, I do not have much to report. My MS has me presenting similar to a stroke victim, with rt foot drop, rt arm and grip weakness, weakened rt side, but with relatively normal left-sided strength. I am my own control group I guess. My condition has been fairly stable or slower decline over the last five years. I had already noticed some improvement using vibration exercise (that I wrote about) which is supposed to improve circulation and strength in nerve-weakened muscles. I am hoping for continued improvement combining it with IBT.
I do have one nasty symptom though of a sting that I get in my upper right neck that likes to torment me, especially if I am trying to sleep. Its an odd sort of MS thing that feels like a giant mosquito is biting my neck and sends a tingling burning sensation down into my arms. Oddly, it causes increased feeling and muscle strength rather than the opposite but is not pleasant. Some kind of scaring thing, a frayed extension cord trying to work? The attacks are positionally aggravated but not necessarily triggered, thus I've had to sleep only on my back with my head elevated for some time now (like I’m trying to prevent some wires from touching). With IBT, I am pleased to report that I can now get to sleep with a normal pillow and can actually sleep on my right side. Not once, have I had to get out of bed to take some Lyrica and sit on the couch for an hour waiting for it to dampen the stings.
So I'll wait to see if in the ensuing weeks I see any more differences and post my progress. for the time-being, I give IBT a thumbs up
