Hi Warwick
I have only been on 50 patches but sometimes wondered if I should be on stronger ones. I did not broach this with the Gp's in the group practice, because I wanted to keep below the radar: they tend to tell me to stop after 5 years (already done 6 years with a few very short breaks) or the other usual advice of stopping at 60, which will be later this year. I have started cutting the patches in half to see what happens, partly to appease the GP's and partly because I do not feel great anyway, so would like to know if a half dose makes any difference.
I suppose you could try a lower dose and see what happens. I think part of the issue is that it is difficult to get prescriptions unless you can show that the lower dose is too low.
There is definitely too much trial and error!
