I m currently on Seroquel XR 300 mg and Lexapro 30mg. I already have some of the side affects that gabapentin warns about. I haven t begun taking this drug yet. My initial dosage is to begin at 300 mg at bedtime. 5 days later another 300 mg in the am and 5 days later 3, 300 mg everyday. I ve read some of the side affects patients are reporting and I dont like the sound of them. I already have many of the side effects including drowsiness, drymouth, feeling lethargic. In the past I ve been suicidal and suffer from a host of mental health conditions including anxiety, major depressive disorder, aspergers and a few others. I m waiting on a call from my psychiatrist to see what she thinks. What are your thoughts?
