Been off analogs for about 2 months. Lately I have been waking up and have alot of mucus usually clear or a bit yellow and my lungs feel tight and a little weazing. Also I have a hard time vaping when I wake up, harsh cough but subsides after a few vapes or a few hours after waking up. This has been happening for the past week or so. 18mg juice various flavor. Does this sound like a delayed PG allergy? I have no ill effects during normal hours when I am awake with vaping anything, it is just in the mornings recently I have had issues.
