Well, they are in the post so hopefully it all begins tomorrow...or Wednesday being as Cornish post still gets delivered by horse and cart.
Experiment, you say daft? I tried that with decaff coffee on my hubby, he never notices. That, however, does not carry the same life threatening risks as your test! How long have you been trying her out on the no nicotine?
On the 'mixing your own' front, how does that work? Is that for flavour combinations or for nicotine strengths?
