Reading Slump

I haven't read much of anything since I finished that RNP book a week or two ago. I have just been very tired, and unable to get up for it. Weirdly I've started two books (one was started and then misplaced during the holidays, last year I think) and the other I did read a few pages of last week. But I don't remember what I read in the first, and I haven't gotten to the part where you are 'sucked in' in the 2nd. But I am wondering if my lack of reading is related to my 2 or 3 days of bad mood. It's either that or the old standby, hormones...
