Awesome! I also think flushes can be done closer together than 2-4 weeks.
I start getting a few sharp jabs in the gallbladder/liver area about 5-7 days out from a flush. I'm guessing that this is due to older stones moving foward to occupy the empty spots left by the flush. So if there's any discomfort, there's probably more stuff ready to come out.
The heat and vibration also sounds like a good idea. As a newbie, I can only vouch for occassional stretching and massaging. Last time, I rolled on my back after 45 minutes on my side and rubbed under my ribs. Everything had been quite inside. Immediately after, I felt a bunch of gurgling sounds travelling from my right ribs downward. Sometimes a little external help gets the train moving.
