This blows...

So I had spent 5 months of the last year smoking nearly every day, usually 3 times a day, then when the new year arrived I said I needed a T-break because it started having absolutely zero effect on me. At first I did 5 weeks, it changed nothing. Got "high" and there was like barely any feeling to it. Then I went for 11 weeks, this time it was a very mediocre high the first session and then nothing for the next attempts. I had read that this amount of time was supposed to be enough to re-start the whole thing. How many months am I supposed go without it now? 6? 9? This fucking blows....
