Bought a subtank mini to test out sub ohm, chase some clouds and maybe even get familiar with building coils, but I dont know about sub ohm. Its harsh! It burns my throat, makes me cough and I dont really see any difference in my clouds. Am I missing something? The flavor is a little better, thats the only positive difference I notice, but I dont really want to get my throat used to this harshness (didnt quit smoking to tear my throat up), is that what people are doing or is there a way to make this smoother?
