I am new here can't explain what is going on in my body.  Maybe someone can help me understand this.  There are periods over the last couple months where my body is in a relaxed flow state and if I see an email about a local dharma talk or see a new book/material.  My body just lights up and feels great.  It is like a sense of "coming home".  Warmth sensations, afterglow.  Sort of like the feeling one would get after really good sex.  It happens sometimes when I think about meditation.  I have really wanted to practice more over the last several months too. 
Any help would be appreciated.

My guess would be that you have had positive experiences with meditation/Dharma and now have a dopamine hit with things related, this is a good thing.

Thanks.  Good article by Gary. I saw his interview at Buddha at the Gas pump.  Very coherent mind.
