Clonazepam
"I was put on Klonopin about four years ago.  It worked very well until I made a change from 1 mg that was blue to a .5 that was yellow, both by Sandoz.   I was trying to make it easier to break in half and lower my dose. After about 4 months I began to notice as soon as I took the .5 yellow tablet, I would break out into a sweat all over my body like I was having an allergic reaction.  It was during this time I developed Burning Tongue Syndrome.  On the blue 1mg it began to feel like icy hot was put on my legs.  I was trying to see if anyone else had these symptoms. I may have gotten a bad batch of Generics but if I have it was on three different refills.  Something has changed with this medication."
