Dear Loynata, sorry I didn't see your post till now. (I am so busy, I don't get to read the forum as much as I wished). It seems that you made the neder in a very smart and safe way. You didn't make it directly against the behaviors, but rather
around them, in such a way that you know you can for sure keep them. Very smart. And like Will said, the trick is to find the nedarim that work for you
and renew them before they are up. Make sure to write them down, so it is easy to renew. and if you find a loophole, quickly make a neder to block the loop-hole, and add it to your list... Before you renew the nedarim, check if perhaps something needs an update, and add it in to what you wrote before making the new set of nedarim.
As you find what works well for you, you can make the nederim for longer and longer periods of time.
For a frum addict, nedarim is truly a wonderful solution - and pretty much a
MUST, and I believe they
can help even for the long term, if the nedarim are made wisely...
But of-course, continue with the 12-Steps as well. That will teach you a whole new attitude in this struggle which will make the whole thing so much easier (and easier to keep the nedarim too!
)
