I did for the first one as I say before it took me a very long time to get down to passing a 15ng. My first I just drank tons of water leading up to the time of test an put2 berocca in the water to make my urine more urine colour as with loads of water it just came out clear otherwise. This bought me just another week to completely flush my system. I was a heavy user so it took additional time for me to become clean as it was at 6 months an I new I just need the extra time to be clean. I will say now I’ve completely kicked the habit and don’t intend to ever go back to smoking, I had my yearly medical last Thursday with urine test and obviously it was clean but this time I struggled to provide a sample purely because he was staring at me trying to provide lol I got there in the end tho with the minimal amount needed haha. But 6 months man, that’s crazy isn’t it but I’m living proof it can stay in that long.
