Guaifenex and wednesday night

Hmm... but for me the ethex brand guaifenex perscribed to me has been like speed, i forst got it on a wednesday night took 2, which was recomended by my doctor, and i didnt sleep or eat a full meal until friday night when i didnt take the second dose of medication, and also drank a little that night. During those few days however i did continue taking my medicine, but sometimes not 2 twice a day. Basicaly i felt like i was on some amphetamine or speed for about 2 days straight. However i did not find the experience to be of any nuicance. But now about 4 days after starting the medicine, i have a rash on my hands and feet and the symptoms comply with hand foot and mouth disease, but actualy i think this is the real sickness i was prescribed to guaifinexe for, since the doctor never gave me an actual name for the virus
