If you DIY you could easily help her lower the nic level without her even really noticing.My sister-in-law was a success, but the problem now is getting her to come down from 24mg nic which she's been on for nearly 2 years! She says it works so why change it..... suppose she's right but I'm sure she would be just as happy on 12 or 18.
Edited to add: Uh, and of course: Welcome to EFC - I'm new here, too.
