Sorry you have been dealing with the dizzies. I just had a bought of BPPV myself, and was lucky enough that my chiropractic neurologist knows the Epley and saw me every day (without charge!) until we could do the dix-hallpike without any spins. I am now back to my non-dizzy self.
I would call your ENT doctor for advice on this question. I would also try to find someone like your doctor or a PT who knows the Epley to do it with you to make sure you are doing it correctly. Sometimes we patients may do it the wrong way, or have our head tilted the wrong way and the crystals may go into the wrong canal...
Most doctors will tell you to do it on your own. I know, I was told the same thing by an ENT who gave me the impression that she couldn't care less about me or my silly dizzies.

But that's all behind me now, and I hope this will be behind you very soon too.
