The REAL codeine causes me to have esophageal spasms. They are VERY intense and EXTREMELY painful - so painful that the first time I had them, I was quickly rushed by ambulance to the nearest ER because the pain and symptoms are the same as a heart attack. I would recommend that anyone taking codeine for the first time in any form use caution, especially if you have any type of GERD or reflux issues.

Is it possible that I would somehow be immune to the effects of DHC? I have always found codeine to be a big help to me but I recently tried some DHC because I had heard it is more pure and has less side effects i.e. constipation. The problem was it seemed to do absolutely nothing to me. I took a 40mg and about two hours later two more 40s. These were not time release they were genuine DF118. They had like zero effect. Expirey date is 1/11 so I know that isnt it. Could it be cuz I usually take codeine on an empty but took these with food?
