Sufficient Sleep

I can't say I sleep enough, because sometimes I sleep a lot, sometimes I sleep a little. It depends on many different factors. But, as is true for many other people, I know more or less (note:  "about" could have a different meaning here) how much sleep is sufficient for me. If I sleep about 8 hours and I sleep well and deeply, then the next day I feel good. Seven (don't start a sentence with a number) hours is also enough for me, but when I sleep like this I know that the closer the evening comes, the less vigorous I will be. The worst thing happens when I divide my night sleep into parts:  Sometimes I wake up in the middle of the night or closer to the early morning and feel good. It seems to me then that I have slept enough to start working or doing something. I begin to learn English or read books etc. It's a tricky thing, because I know that this is an illusion; my drowsiness will come back. And indeed, soon my enthusiasm drops to zero. I yawn terribly and fall into bed. Make a guess what time I usually wake up then!
I suppose I ought to try to change these habits, especially knowing that I always dream about early morning as the time for doing  good things such as reading or learning languages. One needs to make just a little effort: to go to bed on time in the evening and sleep. But the easiest things are usually hardest. So it goes.

I can't say I sleep enough because sometimes I sleep a lot, sometimes I sleep a little. It depends on many different reasons. But, as many other people I know about a quantity of sleeping that is sufficient for me. If I sleep about 8 hours and I sleep well and deeply, the next day I feel good. 7 hours is also suitable for me, but in this case I know that the closer the evening, the less vigorous I am.

It seems to me that I slept enough to start working or doing something. I begin to learn English or read books etc. It's a tricky thing because I know that this is an illusion, my dream will come back. And indeed, soon after this my enthusiasm falls down to zero. I terribly yawn and fall in bed. Make a guess what time I usually wake up in these cases.
