Warfarin Sodium and sunburn

I have been diagnosed as a homozygous Factor V Leiden mutation and will have to be on warfarin for the rest of my life. I feel really dragged out and tired and need a couple hours of sleep midday. Sometimes though I wake up at 4 am and am wide awake. It is not dependent on my nap. In general, since going on warfarin I feel generally weak and tired. I sunburn more easily and it takes longer to heal. They do not say these are side effects but it sure seems odd that it has happened since warfarin 8 months ago.

My husband has been on coumadin for about three months and recently I noticed that his face is very oily, especially around his nose. I also noticed that his nose and cheekbones are very red, almost like sunburn. Sort of like a raccoon. Has anyone else noticed something like this? Also, it seems to be difficult to keep in the "zone" that the doctors want to keep him in. Any suggestions on how to make this easier?
