I've been abusing codeine, cpm syrup since past 5 year's. Now I'm planning on quitting codeine cold turkey. Also I have been abusing Pregablin 150-500 mg since past three weeks along with codeine. I took pregablin solely for recreational purpose as it potentiates codeine a lot. Is it safe to quit pregablin cold turkey? If not, how long should I taper Pregablin before i completely stop it? I have abused it only for three weeks. I have never had a seizure in the past.
