Whenever I read, I get neck cramps. I tried looking down at the book, I tried lying on my stomach and looking forward at the book, but I still get cramps.
Is there a trick to not get cramps?
Though I haven't tried them there are prism reading glasses that might make it more comfortable (something like this, perhaps), or you might try large print text that would allow a more comfortable reading position. Could the issue be tenseness, however? Try relaxation techniques.
Try sitting on a chair, then putting a big cushion or pillow (or two) on your lap. The pillow will raise the book level higher, and you won't have to strain your arms or neck to read it.
