Good Morning. Have your sleep habits changed?

I've struggled with insomnia for years.  I was taking Ambien but after a few scary episodes where I got up and did stuff and didn't remember the next day I went off it and on Lunesta.  That worked but it made water taste terrible and that was when my headache started so I thought it was because of the Lunesta because that is one of it's side effects.  I went off the Lunesta and my doctor wanted me to wait at least a few weeks before trying another sleeping pill.  Surprisingly I have been able to sleep without a sleeping pill but it has been getting worse.  Even with the sleeping pill I get up just about every hour on the hour.  I have been taking Melatonin but I may have to go back on a sleeping med.
I also sleep with 4 Chihuahuas.  For the first year I lived here they didn't sleep with me but then I made a mistake and let one in and that was all she wrote.  I've always sleep with Tazzie and JJ but 2 dogs were no big deal.  Four is.  They take up the whole bed and when I get up to use the bathroom they have taken over my place in bed.  I actually find myself sleeping surrounded by dogs, one on each side.  I really wish they wouldn't sleep in my bed but when I don't let them in they sit at my dog and cry, bark and scratch the door so I give in.
