I was on hydro morphone before. It did depress my appetite somewhat and I think the tramadol is as well, but that is really not a bad thing and my dog is delighted.
We have a raised bed as well. When we got it several years ago my husband made me a step platform so I could get up on it easier. Our Boston's were elderly then as well so needed the help also. I'm only 5'2" but my husband is 6' so the bed is ideal for him but if I sit on the edge I can't reach the ground.
