"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."
