Even though it's not recommended, it's sometimes the least painful option. :S Twice last year I went down in dosage on my meds before I met with my doctor because I just couldn't get a hold of them fast enough - and getting them to agree to letting me go down in dosage AND change med took some time. There was no way I could live with the side effects that had begun with my antidepressive after an increase in dosage though (involuntary muscle spasms, very often both night and day, and outright kicking in the night).

Hope your troubles get helped by the change! Executive dysfunction issues because of lack of correct medication sucks.
