"zolpidem worked well at the 5mg dose for about 3 or 4 nights.  then i noticed my lips were dry, mildly cracked, and tender.  gradually i noticed that the tip of my tongue felt as though it had been burnt. i ignored that as i drink hot coffee.  on the 4th day i used a listerine-like mouthwash; the result was an immediate and severe reaction:  the inside of my mouth became bright red and swollen. my face broke out in scattered red spots or streaks. once i had spat out the mouthwash and the pain had gone down, i noticed that my eyes, or the tissue around my eyes, also felt dry and sore.  two days later, the reaction is gradually clearing."
