			I have had a similar problem for a long time.  My tablets (& my phones) all caused me enough problems that I couldn't sleep at night.  So I had multiple readers, two of them eink and one (or more) tablet(s).  Since I bought the Nook HD+ I can read right up to bedtime with no problem.  Now the Nook is the only reader I use.  Check it out.  YMMV.
