I am sampling all these different tobacco e-juices lately. I have one in my tank now that I do not really care for, and I want to try something else, but the tank is almost full. I don't want to throw it out, because I may like it in the future when my taste is fully back. No way this liquid will ever go back into the original Hangsen bottle. What do I do now? I don't like waste. Any advice folks?
