I was practically chain vaping when i first came off the stinkies....i think this is pretty par for the course...till things settle down. I started at 12mgs in my MTL tanks, & 6mgs in my DTL tanks...and i still am for the most part. My consuption is somewhat less, i probably get through about 4ml/day with MTling...and maybe 5-10mls DTLing. I'm getting all the nic i need from that, but everybody is different.
I've seen some folks post that they can get through 200mls a day, so i don't think you've got much to worry about
@Jonsquonk!
Just keep on tooting, and hopefully you'll soon stop the smoking, mate!
Good luck!
