Lots of great advice. I am now day 16 of cold turkey and it has been much easier after the first few days although you have a bit of time under your belt. All the symptoms sound perfectly "normal" for withdrawl. The insomnia was/is the worst for me. I am not done with it but am sleeping abit more than I was when I didn't sleep at all.
Some day you will feel it being gone and you will see the world through different eyes and it will be a great feeling. You just have to get through this first.
Add my agreement that cold turkey is the best. All the others are just more dependency.
