Recently the increase in the dosage of Prozac have been causing sleep disturbances. I upped the Seroquel ( that I take for insomnia) from 25 mg to 50 mg and I still wake up in the middle of the night. I"m wondering if increasing it to 75 mg or even 100 mg would help? Coz I've heard the sedative effects of Seroquel decrease with increase in dosage..
