Hi!  This is my first post.  I am about to embark on my 3rd attempt at 
vaping.  After spending tons of time here (thanks everyone for all the help!) I realized I needed a decent set up & decent juice.
Last week I went to my only local vape shop & they set me up with an eGo-t.  (OK for now, but I've promised myself a pink Twist & purple Spinner once I quit smoking!)
I have smoked 1 PAD of Virginia Slims Ultra Lights for 20+ years.  They sold me 18 mg 80/20 juice & said that is what a PAD smoker needs.
I cannot vape the stuff - at all.  My ultra Lights barely have a TH - this juice sends me into a coughing spasm every time I try it.  I've tried 
vaping it all different ways.  The only way it doesn't is if I vape so little that there is nothing to exhale.  I had the same issue on my last attempt w/ GreenSmoke & Blu - couldn't tolerate the regular carts - had to use the lights & ultra lights.
So I understand the next step is to find "my" ejuice.  I have ordered quite a few samples & small size bottles.  Hopefully they will start rolling in tomorrow.  I ordered them all @ 12 mg.  I also got some VG & diluted my current juice - about 2/3 juice to 1/3 VFG & it makes it vape-able, but it taste nasty.
Now I'm wondering if 12 mg will be strong enough to replace smoking?  Should I also be trying to find an 18 mg I can live with - maybe 100% VG?  Thank you for any guidance & assistance you can offer.  I'm not giving up this time!
