Thanks ExXB,
Forget patches, these e-cigs are fab, you still have something to twiddle in your hand, something to puff at, get a 'throat hit' from, inhale etc, it's not actually that difficult because I'm still getting my nicotine fix but without all the other nasties that cigarettes contain.
Out of habit I'm finding myself reaching for a packet of fags that isn't there, it is now 2100, Tesco's is open until 2359, but I won't be going across there!
