“I never made a Neder. I just always ate only CY because they sell it all over my neighborhood.”
Ofcourse- In hataras nedarim it says the following:
“…???? ?????? ????? ???? ????????????? ?????? ????????? ????? ?????????? ???????? ?????? ?????…”
“…or any good thing that I have performed three times but without specifying that the practice does not the force of a vow…”
Apparently just “doing things” holds water.
