I was addicted/borderline addicted but definitely could have become worse. Was using everyday, had 6-day binges and blew through a half-gram in two days (fortunately, I was in odd situation in which it was abundant and basically free). My use and other things going on in my life came to a boiling point at the end of January when I had a complete breakdown and spent five hours in a trance like state, chain-smoking, gaunt, skin and bone, sores all over my face and chest, unable to really move or speak or sleep, rocking backwards and forwards in my underwear on my dealers living room carpet while about ten guys organising a massive deal around me.
It was a wake up call.
I used other drugs to keep away from it. I told my guy not to sell it to me and I took lots of amphetamine sulphate along with cocaine, ket, mdma, xanax. I wolfed down anything but Tina. I wouldn't recommend it - I managed a month until last weekend when I binged. Took half my face off on Wednesday and I am ending a three day bender this eve. I am planning to use Zopiclone to sleep through my cravings.
Tina has left me a bit of a shell but I think I can stop but I just love it. Good luck mate.
