I have never been someone to lie down during the day - until I got ME. These last 12 years have been unbelievable, the hours upon hours in bed. So weak I even ate my meals in bed. Even today I still bring meals to my bed. I have noticed just this last year I have been getting sore in the back. I have never had a choice, but to lie down. If I don't lie down my body will collapse me down. How is your back and are you able to get by just sitting or do you need the lie down kind too. ?
