Hi again.
I forgot to mention that for mood-disorders, Lamictal monotherapy has been found to be significantly more effective than Neurontin. Together, they make a good combination in treatment-resistant cases according to NIMH studies.

Journal of Clinical Psychopharmacology
December 2000 (Volume 20, Number 6)
A Placebo-Controlled Study of Lamotrigine and Gabapentin Monotherapy in Refractory Mood DisordersFrye MA, Ketter TA, Kimbrell TA, et al
J Clin Psychopharmacol. 2000;20:607-614
The standard pharmacologic agents used in the treatment of bipolar disorder (ie, lithium, divalproex sodium, and carbamazapine) are all limited in terms of effectiveness and side effects. Refractory affective illness is therefore a particularly difficult issue for clinicians and patients. The authors attempted to examine the efficacy of 2 third-generation anticonvulsants, lamotrigine and gabapentin, in the treatment of refractory bipolar illness. They examined 31 patients with refractory bipolar illness and placed them in a double-blind randomized series of 6-week crossover trials of lamotrigine, gabapentin, and placebo. The patients responded most robustly to the lamotrigine, with a response rate of 52%, vs rates of 26% for gabapentin and 23% for placebo. The mean dosages were 274 mg/d for lamotrigine and 3987mg/d for gabapentin. The medications were generally well tolerated, with 1 patient developing a rash that necessitated discontinuation of lamotrigine. The authors concluded that lamotrigine held promise as monotherapeutic agent for the treatment of refractory bipolar illness, whereas gabapentin seemed to hold more promise as an adjunctive agent.

What little there may have been when I first raised the dosage from 200mg (the average effective dosage for depression) to 300mg dissipated within one or two months. With this information in mind, I would advocate your giving Lamictal a try. Generally, it produces the least amount of cognitive changes among the anticonvulsants and unlike the others, possesses true antidepressant properties.
