thank you for the welcome clint and the advice :-) i will def reduce gradually as suggested and i hadnt even considered the fact that i could be withdrawing from the chemicals....its hard to believe that i have given up smoking, having tried so many times in the past and failed and would be climbing the walls by now with nicotine replacements but already i can sit next to my mum smoking and im like ughhhhh...fingers crossed its vaping for me from now on :-)
