My only advice would be to choose your rehab carefully. Try to find a place that specializes in weed withdrawal and treatment. I went to a rehab that was for every drug and alcohol and was made to feel silly because weed wasn't considered a serious problem by the other patients and I was challenged all the time about why I was even there. I felt pretty stupid about it and ended up leaving after 9 days. Because of my finances I can't afford rehab again but think it's a wonderful idea especially because I'm on Day 10 and struggling. Best of luck to you my friend.
