I understand your frustration. You're wanting to stay away from cigarettes, using a lower tier setup that you were probably recommended, and you're genuinely not enjoying the issues that come with doing so. The good news is, we're in a completely different generation of vaping now. With a little patience, and the right resources for information (you're in a great place here at ECF), there is a much better experience awaiting you.
There are tanks that will not flood on you, there are mods that are adjustable to give you just the right throat hit to make you feel comfortable and satisfied, and there are juices varying between Bubble Gum and Steak Seasoning to meet any flavor desire you wish to have. You simply need to be patient and not allow the learning curve to discourage you.
In the end, you will find that the very, very minor issues that are still involved with vaping (more being resolved monthly as new products are released) are much better than the cons you have with smoking, or going back to smoking.
Deep breath, mind wipe, and let yourself research a bit to find a better setup that suits your needs. It's there.
