I've been following this forum for several years now. The last time I signed in (about two months ago) I saw a post regarding the usage of NAC (N-Acetyl-Cysteine) to control the urge to pick. I've now been taking 1200 mg of NAC for two months. To my complete surprise (and utter delight!), my picking episodes have almost completely disappeared. My skin is healing and I'm beginning to feel "normal" for the first time in 5 years. This is the only thing I've changed. My life continues to be stressful and I still face many unresolved issues that I'm sure counseling would help me with. However, due to lack of health insurance, counseling is not currently an option. The single change in taking the NAC has literally changed my life.
I don't know if it will work the same way on other sufferers, but I think it's worth a try. Please give it a shot. God...I feel human for the first time in ages. I'm even hoping I'll be able to wear tank tops and shorts this summer.
