For the last few days I have started to have issues with my jaws being very tight/clenched and they are also very sore in the mornings. I assume that's from clenching my jaws and grinding my teeth in my sleep. I found an old thread on this issue and read through it but did not find any real resolution to the question there. My feeling is that I may need to reduce my nic level as it seems to become worse after a long vaping session and also worse at night. I've only been vaping for about 10 days. At first I used 24 mg in the morning then switched to 18mg for the rest of the day. Now, it's just 18mg all day long. I was wondering if anyone has had the same issue and, if so, how did you resolve the issue?
