I stopped praying for a while when I was still a believer just to see if anything would change. I guess that's the scientist in me - always experimenting. Nothing changed... my life didn't go to hell, and things were going pretty well. I can't remember if I ever started back up praying again. I don't think I did.
Sometimes I will get the urge to pray when I get anxious about things. I think it's just from years of conditioning. I haven't actually prayed when this happens, but usually I'll kinda talk to myself in my head encourage myself. I wish there were a supreme being looking after me, but I just don't believe that's the case so I don't see any sense in pretending he/she/it/they exist.
I have done a couple of hilarious/blasphemous dinner prayers, say for Thanksgiving... but that was just for fun. :)
