Please could someone tell me how the patches are supposed to work? I'm about to start my 4th week of 21mg and will be getting more on Friday. The doc wasn't very helpful at all, in fact he flippantly said "some people have the odd one or two a day while they're on these" as if it was okay, er-hum (a tad careless and neglectful methinks as those people are probably/definitely the ones who fail to stop....). So anyway, do I get weaker patches on Friday, or do I stay the same for a while more? And when the patches stop altogether (and this is what I am most scared of) do the cravings kick in with a vengeance????? Please can someone give me this info if possible, to stop me worrying about what hasn't happened yet?! Thanks!!
