Yeah I think that was my mistake. Seems to work much better now and the taste is good. I think that is what happened I got a dry hit and was coughing my guts up. But it is working fine now and is rather pleasant. Hopefully I'll be able to use this all the time and finally get rid of my nicotine stained fingers and nails. If I can give up smoking with this it'll be the best £50 I've ever spent.
Stick to it man! You'll feel better in yourself in about 2 weeks-ish.
