I think you and I are having the same problem.
I've heard someone recommend to have the truck running while doing it, I just don't get why you'd do that.
Also heard a recommendation to open valve first, then have someone push and hold while you close the valve. I don't know why.
I had a good friend tell me that I should just keep on bleeding, to put a big bottle or two through it. How many squirts should it take at the far wheel(driver rear)?
