I been taking this medication for about 2 weeks now, I am experiencing a numbness on my cheeks, nose and lips. My tongue seems twisted when I talk and off course trouble sleeping. Am I having a reaction to this medication, my doseage is 300 mg. 1 at bedtime 1 in am. I did skip the am dose today (10/20/12) and still have the numbness in my face, I was itchy alot but that seems to have subsided. The Pharmacist said to use benedril. I did go to the ER, they didn't seem to think that I was having a reaction. Is this just getting used to it in my system or is this a reaction?
