I think the whole idea is to keep your own energy on the cards, so doing a  reading for yourself shouldn't be a problem.  Also they say to sleep with them under your pillow or bed so the deck gets to know you.  It saves your energy and will give you better readings.

I believe that you should sleep with your cards next to you or very close.  Mine (I felt like ) were calling me one night that they were in the other room and I didn't feel OK until I had them next to me.  sounds strange but we need to be near each other to continue the conection we have.  
      I am not sure about reading for yourself yet.  I do think that your conection might be too strong to read right  but then again you know the question and you also are reading what you want to hear.   Just be careful and try not to read only what you want to hear,  but  try to see what your cards are telling you.

I am new too (to Tarot), but I read for myself all the time as a way to learn - I love LisaLisa's reply and agree with her "take".  I am also a numerologist and I find that my readings are best when I step back from what I think I know and read what the numbers say, I am sure the  same holds true with Tarot.

l have read for myself quite often.. during times of stress and found that the same cards keep coming to me until l have resolved the issue.

As I'm not a terribly social person, and those that I am social with would not quite understand the need for tarot, I am forced to do readings only for myself.  However, that seems to be fine for me, as I have found great relief in them.  I do try to be honest with myself, and often find that the cards "take me to task" about many things.  For me, I usually know the answers anyhow, but the cards really give me a focus point to meditate on, and in the end, I find that my life has improved by leaps and bounds.  It's an incredible self-help tool.
