UGH...slowly, but surely

I am more than 3 weeks post-op, and my recovery is slow going. I am tired and uncomfortable most of the time. Not exactly painful, though I am at times, I am mostly just weak and tired. I am trying to maintain my fluids and eat regularly, but despite that I continue to lose weight. I have lost 20 pounds since surgery. I'm not unhappy that I lost some weight, but I am sorry that I have lost it so quickly, and it continues to drop. I am anxious to feel better and get on with life already.
