How long should it take? I replaced the rear brake fluid (after I accidentally drained it out while replacing the rear brake pads...oops!) and methinks all I need to do now is to bleed the brake to get the lever to feel hard again. Tried bleeding the brake for about 10ish minutes (maybe 7-10 times) and the lever is still soft and soggy. Anybody have the same experience? How many times should I have to pump and drain out the air bubbles before it starts to feel hard?

If you drained the rear nearly completely, it will take forever and ever and ever. Really.

Ok, I've bled it 3 times letting it sit for an hour in between bleeds. Bled it about 15-20 times each time. It is still soft and mushy. Could I possibly be missing something else? I'm not getting air bubbles any more when I bleed it. What is this reverse fill you speak of? Does it make it so you don't have to bleed the brakes? I'm all ears...

It took me a long time to bleed the front brake on my LX150. Not to be impolite, but are you sure that you are bleeding the brakes properly?

When you squeeze the brake lever to get the air out, you need to quickly tighten the bleed nipple on the caliper as soon as you get straight brake fluid with no bubbles. Otherwise, the air will stay in the system.

The steps that I followed are outlined in my posts here: Help with Brake Fluid

Those are for the front brake on an LX150. Your rear brake may be a two person job - one to close the bleeder valve and one to squeeze the level
