I have noticed that I have a mixture of good vaping days and bad vaping days. Some days I can't get anything to work together - my attys flood, the draw gets too tight, there's not enough TH or vapor, etc., etc. The negatives seem to last all day. Other days everything comes together - perfect hits, attys working perfectly, flavors taste great. In other words, no problems at all. Does anyone else experience these different vaping days?
