Sleep Machine

So after waiting on pins and needles to find out if we could get Carlos' sleep machine before the deductible rolled over - we got it!  It was down to the last minute but the home health equipment place came out last Friday and got him all set up.  Apparently he only has to wear to 4 hours a night at a minimum.  I wasn't available (was soaking in the tub) when they came so couldn't ask why that was.  He has been using it but does take it off in the wee hours of the morning.  He says he feels a little more awake in the morning since using it but whether that's related to his imagination or truly an effect from the machine, remains to be seen.
