This could be a bit of a different issue with your specific type of license.and the cargo.you may need to check with the CDL governing board and have to go by thier guidelines.for any other driver,i was on neurontin for over two years and had no problems at all.it all boils down to how you actually feel and and feeling that you have some level of impairment really.when using the normal class license,this would be a judgement call.yours would be the licensing boards call.you know what I mean.you just have ALOT of restrictions with your particular type of license that a (what IS the new classsification of the normal everyday type of license now these days,D?)would not have to follow.FB
