Lost welcome to SR!!! Here you will without a doubt find the help you need to begin your process of detox and recovery. You have a problem and have admitted to it. That is the first step to recovery. For the sleeping problems I also recommend the following:
1. Glass of warm milk at bedtime
2. 5mg of Serotonin (you can get it at GNC)
3. 1.5 grams (1500 mg) of GABA (Also available at GNC)
4. Warm bath
I took this combo my second night without pot and before I knew it I was past out in the couch. If it doesn't help then I suggest some of the more aggresive methods mentioned by Vinter. However, you need a prescription for those meds...
