Ok, so I ordered my VVV mod from kalamazoo vapor shop and I'm having trouble with the vape! The mod works perfect, I'm very happy with the quality, the customer service was OUTSTANDING, but the vape seems really harsh. I got the 5volt regulated...upgrading from the 3.7 I started on because I have seen so many people talk about how 5v is a very sweet vape. I'm using the carts that I'm supposed to use with the mod, but the juice seems alot harsher on the throat. I DIY my own juice using an e-juice calculator online. I'm doing a 50/50pg vg mix @ 20% flavor. Can anyone give me some advice on what I could do to make the experience less harsh? Oh, and my nic level is only a 12.
