When I first completely tapered off of Seroquel XR (due to twitching muscles and clenching my jaw) I did so over the course of 3 days. XR 300, XR 200, XR 100, nothing. I don't know why your doctors are tapering you down so slowly if your side effects are that bad--plus Seroquel at doses less than 300mg can be very sedating.

I'm currently on regular release Seroquel 200mg AM, 400mg PM.

When my current doctors weren't listening to me about how poorly I was functioning, I supplemented my low dose of meds (50mg Zoloft, 100mg Seroquel) with Yogi: Ginkgo Clarity tea, and WellMind: Mental Focus tablets. The tea helped more than the tablets.
