Cholesterol now super high - need to taper

For the last 2.5 months, I’ve been taking Seroquel XR 50 mg twice a day for somatic anxiety. Last week I increased the dose to 150 XR a day (100 at night and 50 in the morning) to cope with a too fast taper of a benzo. My cholesterol skyrocketed in that time so I want to get off the Seroquel as soon as possible. But I just got burned by trying to wean off Klonopin too fast. Can someone suggest a safe taper of 150 Seroquel XR for me? I don’t want to be trying to taper this for years while my heart health declines.

I’m also on 1200 of gabapentin to help me taper from Klonopin and 120 mg of Cymbalta for chronic pain.

Thank you!
