Off my injection and on pills

I finally talked the manager of the group home into letting me get off the injection of Invega and on the pills. I have always felt like that injection may have contributed to the voices I hear. I have been on them one week and only heard maybe three voices this whole week. So I am wondering if the shot had anything to do with it. Technically switching from the injection to the meds was a minor decrease in meds. Just wondering. I used to get the 217mg a month injection. I went down to like 168 and then down to 78mg a month. Now it equals out to be 2 1/2 mg per day. The voices has lessened each time I decreased the med.
