My sister was on seroquel.... she was taking 200 mgs in the morning and 600 mgs at night. It was insane! She would fall asleep while eating chocolate and it would just drip out of her mouth at around 10pm.
Is she going to take it only at night? Is it's main purpose just for anxiety?
My guy was given ativan for anxiety when in rehab... low dosage, but helped with the creepy crawlies from the opiate withdrawal and sleeping.
I think many of the issues with seroquel should be brought up with the doc... especially the ED.... I think your daughter will appreciate that too.
Look into the kava kava root...... too.
