Olanzapine Withdrawl

I was on Olanzaapine at a low dose 2.5 mgs for about a month , decided that it was too dampening, I felt slower, calmer sure, but dumb as a bag of rocks (took it for symptoms of anxiety/panic). Rn Im on day 4 and my sleep shcedule is awful, I fall asleep in the middle on the night at around 3-4am and am only able to sleep for like 6 hours at most, Im not getting deep sleep or rest. I also feel for lack of a better term a bit 'off' if Im being honest. A bit anxious from time to time and really tired. I guess I wasn't expecting the withdrawl to be this bad considering the dose and the duration I was taking it for (30 Days).

If anyone has any advice or experience and could just shed a little light on my situation. How long until I begin to feel a bit better and like myself again?
