Yes, we have members here that consider this a warrior's medicine/path and have really pushed it with Kambo, seeking healing and a deepened relationship with the medicine through dedication. There is no one answer to this question except to listen to your body & intuition as holybark has stated. If you feel that you are overusing it, or any other unsafe practice, you should keep a log here of how often you are doing it. That way members of this community can give you advice, if needed or wanted.
