The pub I went to this afternoon to get my mussels let's you vape inside too. So I just sat and puffed away
Yeah theres a few pubs that will let you vape. Most don't like it if you start blowing clouds though so stick to a high PG mix in pubs that let you do it.
Start trying different flavors, maybe a menthol to begin with. Trust me, after a few weeks you won't be able to smoke the tobacco stuff without retching. Now that you've got two vapes you could put you tobacco juice in your old vape and the use the new one for trying new flavours.
Also, like Yossarian said, leave it a good 5 - 10 minutes after filling the tank on a new coil. The more powerful vapes are very unforgiving on a dry a coil and if you get a dry hit, more than likely you'll need to replace the coil. Keep an eye on the juice level as well - you'll want to top up as soon as its empty, don't try to get a few extra draws out of it.
