I'm not on bedrest, but I was literally in bed for about 4 months with hyperemesis. I could not even sit up some days and it was definitely the hardest thing I have ever had to go through in life. It really put bedrest into perspective for me, because I thought about how it would be torture to have to stay in bed if you were feeling just fine. I got headaches from being in the wrong position, I had a bucket because more than half the time the bathroom was too far away.. oh lord, it was awful. DP and I agreed that if our next PG-cy is this bad again, we are done having biological children. I did a lot of blogging, got hooked on too many shows online, read up on so many things related to pregnancy, birth, and parenting...
If I could give you any advice it would be to keep trying new things if you're bored until you find something that keeps your mind off the situation. You can also invite family and friends over to help you plan for the baby, whether it's shopping online together, having them do laundry and keep you company, or just to watch a movie with. And hey, mothering forums are a GREAT way to pass the time. Being in bed is how I got involved, too!
Best wishes for a full-term, healthy baby and easy birth.
