"Limited benefit" is the classic fob off because it means nothing. I would have thought that getting your sleep sorted into a reasonable and consistent pattern should be of paramount importance? If the lower dose of quetiapine suits you and acts as an add-on to boost anti depressant efficacy then this would be ideal but I know it's not as simple as that. I know my son has risperidone to limit rumination/self harm/ suicidal ideation in conjunction with 225mg ven but he is on a low dose(2mg) to limit akasthisia. Doesn't help with sleep though although he takes it at night but he has ASD so things are more complicated and his ruminations are solid and unreachable.

Glad you've got a review next week. Don't be afraid to speak your mind because you will still get that promised therapy. You are just being assertive and not just "taking" whatever is dished out by a wishy washy psych!
