My doc changed my dose of seroquel I now take 25mg at 8am 25mg at 12pm & 50mg of seroquel xr 4 or 5 hours before bed. After 3 days on the 50mg of seroquel XR I will take 100mg of seroquelXR. She also put on 25mg of vistaril take one at bedtime & if it doesn't make me sleepy after 45 minutes I can take another one. Just wondering if this a normal regimen of meds for bd &bpd?
