It’s not necessarily foolish to be without meds if you are managing well without them. Some people are able to use lifestyle changes as you have plus CBT and/or DBT therapy to manage quite well. However it’s no good to lie to your pdoc, because if things do go off, he won’t know how to help you. He will just up your med but not know that you hadn’t been taking it at all.

If you do decide medication might help, there’s more out there than just olanzipine. If you’re worried about brain fog and weight gain you can research other meds that may not have the same side effects.
