There is nothing wrong with it. An addiction (which SI is a part of in my opinion) takes time, it takes a lot of practice. Like I said, shoot for something higher each time. You lasted two weeks, last a month next time. Three months after that. I did that for a while. I lasted two months once and relapsed. It was the worse feeling ever, and also when I did it so bad as stated above. That's when I realized it wasn't worth it. I wanted to prove to myself that I could go even longer. Now here I am at a year and two months and it just keeps adding up, and now I KNOW that I can go without it, even if it's hard.
