Vape juice

So I usually only vape menthol juices because there light and don’t feel heavy in my Lungs. Well they were out of my juice and I had to buy a similar flavor not menthol. I use to vape non menthol but once I felt how light the juice was that’s all I smoked. And I absolutely hate how it makes me feel. It’s very heavy and hard to breath in and makes my throat burn as well. I fuckin spent $30 on the 100ml bottle of juice I’m probably not going to finish because it’s gross. I guess that’s my sign to stop.
