Mark, I take it once a day at bedtime. Perhaps your system tolerates the Neurontin better than mine? It also could be that I have been using a relatively high dose (6mgs) per day of Alprazolam for anxiety and panic disorder that has haunted me for years and worsened after my injury last April. The other thing is I have to work every day and cannot sleep in long enough to feel refreshed. I'm increasingly getting frustrated with the whole situation. Things just aren't getting better and I'm growing wary from the battle I wage each day to function at my job. PCS is sheer madness...I would have NEVER believed this could happen to me. I administer land use law and as laws and statutes change, my mind increasingly fails me because of my inability to retain much in the line of new memories.
