@donfeld - That sounds terrible! There are warnings about the potential for depression on Gabapentin and it sounds like it hit you hard. Obviously, (and thankfully!), not everyone experiences that side effect, but your experience is a powerful remember that it does happen to some people.

Speaking personally, I am playing with the dosage and doing so with a high degree of awareness and caution to see if it is causing similar side effects - or - since my symptoms started after my brother died, if I am just experiencing grief.
