Try to get a yeast starter going with ... EC-1118. (snip) I'm surprised you got much fermentation happening at all with bread yeast.
As much as I agree, I also have to state that I had a 1.120 OG finish out at about 0.999 FG. That took EC-1118, yeast nutrient, and about 18 months of patience.
It was also the best drink I had ever quaffed, so don't despair!
