Bad stomach pain? Purging? Drugs?

Purging once a day would be too much. To be doing it up to 4 times a day would definitely cause severe troubles. You need to go back to your doctor and tell him the truth about the purging, the drinking and the drugs. He needs to know about these things because any drugs he gives you for pain could react with the drugs and alcohol adversely. Glad to hear you have stopped. Hope that means the purging, drugs and overdrinking. Your system needs a good rest. Hope your doctor has something that works on the pain and you get better soon.
