Hello, I have a big problem with concentration and feeling really unwell after reading for too long, is there anything I can do to not find it so difficult and let it affect me so much. When I do too much I feel very out of it and it can make me feel really sick and crash. I don't read too often and this is one of the reasons but I would love to be able to read more. I have a kindle and I think I find that easier to read for me than a book, and both I think are easier than a computer screen, depending on how long I read it for. Has anyone got any ideas, such as eating while you do it maybe to keep up blood sugar and energy etc for concentration. It is that I would like to do it for longer, it would really help I think. Thanks.
