I have a yet to be diagnosed neuro condition that is trending toward MS. i have had worsening burning and stabbing pain in both my feet/lower legs for about a year. I've just started taking Gab a couple days ago. I am also in a job where being out of it is not an option. I probably shouldn't self adjust the dosage (3x daily, 100 mg), but I am going to try taking it when I get home from work, then before I go to bed. It is the only med that has stopped the non-stop pain in both my feet, and for the first time in about a year my feet and legs feel almost normal. So it does seem to be effective. It is encouraging to hear others on higher dosages tolerating it well after a few weeks. I sympathize with the "zombiness" though-frustrating.
