Hi all. I gave up a 10 a day long established smoking habit eight weeks ago after becoming ill with a virus. No problem with cravings but developed difficulty with breathing and wondering if this is a little advertised side effect of giving up ? Am having to use inhaler at times but wondering also if this is part of virus I have had. Well done all you quitters who overcome cravings, I do need to stop eating so much as was putting on weight without trying in the early days.
