Re: lose concentration
Ashiuhto, PLEASE stop posting the same paragraph for correction more than once. Your two threads were identical in content but had different titles. Consequently, billmcd took time correcting one of them, and I took time correcting the other. This is not only confusing for us and for you, but is also becoming a waste of our time.
Please look through all the threads you have posted and delete any duplicates. Please be far more careful with your posts in future. We appear to be writing your entire essay/thesis on insomnia for you, two or three sentences at a time which is really not acceptable, but it's even worse if we end up doing it twice.
Remember - correct capitalisation, punctuation and spacing make posts much easier to read.
