"without going into excessive detail, i&#039;ve been on lamictal for about 5 years. tried anti-psychotics (almost all) but could not handle the weight gain from them. recently i realized that as great as lamictal is, i needed to add an anti-psychotic and just deal with weight gain. but my psychiatrist suggested i try gabapentin before anything else. i&#039;m only on 600 mg a day (been on it for 4 days), and i know my body is still adjusting to it, so this might be a hasty review... but it&#039;s given me a calming feel, helped a little with racing thoughts, but i feel &quot;high,&quot; at times like i&#039;d drank a lot of codeine. it definitely makes you loopy, but i&#039;m just gonna see how it goes. just give it a try if you&#039;re bipolar i and don&#039;t want the anti-psychotics."
