I don't exercise enough but I fell asleep while reading on the internet or Facebook. That would last a couple minutes or so every time. I tried drinking Pepsi or Thirst Quencher or ice water which help not to feel drowsy. I don't understand why I don't want to go to bed and am not comfortable sleeping in my own bed. I guess maybe it is because I miss my husband so much that his presence is not there with me anymore. I don't know. 
Also, I have Tinnitus, too. The noises in my head is bothering me a lot. Oh, well, I try to ignore that.
