Yes I have. I was really sick & hadn't slep in 3 days. I was in pain & just really sick. Finally I couldn't stand it any more. I said the most heart felt prayer that I have eve prayed for asking God to let me get some sleep. I ended up sleeping for about 3-4 hours the most sleep I had gotten in days!!!!!  I was really excited when I woke up because it was the 1st time that God had answered prayer that I knew for sure was answered.   MAW
