I find it difficult to draw up the nicotine fluid into a syringe. It's pretty thick stuff. Seems even more thick than the VG. I asked how to thin out the VG and a guy told me to put a small portion in the microwave and warm it up. That worked great. It sucks right up in the syringe now. I forgot to ask about the Nicotine. Would it hurt to warm it up to thin it out or would that damage it?
