Thank you, I tried cooking longer and it did help but it still wasn't as tender as I am hoping for, BUT I didnt allow enough time before dinner. I only cooked for abt 7 hrs.
So, my resullts were that using less liquid was much better but cooking it longer made the liquid cook away so...... next time a little more liquid (not as much as before LOL. I was filling with liquid to cover the roast) and try to adjust the cooking time to cook maybe 10 hours.
I will also use the high setting and keep checking.
Thanks to ALL who have helped me!!!!!!!!!!!!!
