Thanks so much for the replies. I am using a standard v2 pro so what ever tank that comes with it and my nicotine is 1.8%. I chain vape a lot. I change the cartridge every day or so. Like i stated a week after I stopped I got some damn good rest and now with me already suffering from depression, anxiety disorder, bipolar, and agoraphobia, the depression is hitting very hard from not getting enough rest. I get jumpy with my kids over little things, then I get sad, and then I think about suicide, its a feeling I can beat but it lingers. I just need to know that it will pass.
