Stay away from Epilim. I'm on methadone for pain and I was on Lyrica for nerve pain after a knee replacement but stopped because of the cost and started to feel really bad, suicidal etc. A weekend medical centre doctor put me on Epilim to ease the Lyrica withdrawals but instead it brought on IMMEDIATE Methadone cold turkey I thought I was gonna die. Saw my regular doctor on the Monday he prescribed Valium 5mg immediately and did a complete series of blood tests to ensure that I wasn't ill from something else. I was on 6 Valium a day and reduced it to one a day until the Epilim left my system. It was hell. Turned out that the weekend quack's prescription was totally inappropriate, lucky I have a good GP with whom I have a good trusting relationship, he saved me. I'll be reporting the weekend quack. Epilim can potentiate other drugs but a high dose can take you right past the buzz into immediate withdrawals. DO NOT MESS WITH THEM !
