I wasn't able to get over them by myself, that's for sure! I was delusional, paranoid, and experiencing hallucinations. I ended up hospitalized, and only when I was taken off one med and tried on another did the symptoms go away.
I hope you and your pdoc are able to find a good med cocktail soon, because I've never heard of anyone "getting over" their hallucinations without medication!
While you still have them though, just try to remind yourself that the hallucinations you see/hear are not real. The fact that you have insight is great - I didn't have very much insight during my manic episode.
Sending you hugs and positive vibes.
