I tend to use whichever vaporizer is right for that particular moment. Day or night. I'm a working musician and work from home and on the road and I am both a medical and recreational user. My tendency is to use my Carbon Fiber Omni XL in the .025 setting when I need medicine but also need to get things done, my OmniVong in the .05 setting when I want to relax/play/rehearse, and my Milaana with a generously filled stem for when I'm in a lot of pain, or want to really knock myself out. I rarely use my Alternate. I keep it around because it's good to pass around, but that's all. I only use it solo if I'm really in pain and need a lot of medicine delivered quickly. I find that rotating vaporizers is similar to rotating strains in that it makes the plant work better for me. And let's be honest; variety truly is the spice of life.
