I Love My New Sleeping Bra!

Last night we went to JC Penny's and I got a sleeping bra. It was so comfortable last night...I didn't want to take it off this morning. It was so nice to finally sleep and not wake up in pain ever time I moved. Also, last night I was having some cramping. It started when I got home from work, and lasted most of the evening. I tried putting a rice pack on it, but I was too worried about the heat from it, so I took that off. Eventually I fell asleep, and woke up without any pain. I wonder how long the cramping lasts?
