thanks guys!
I do not have a history of heart disease.  It could be a weird chest cold as one of my employees has this right now.  I also am having some weird head congestion so it is possible that I do have something going on.
I appreciate all the words, thought and support.  I am going to chill on the vaping for a couple of days, and see if that helps.  If not, I promise I will go see my doctor.  
thanks!
		
		
	 
The doc is always a good idea.
I was having the same thing a few weeks into my standard.
More like a tight/full lung thing rather than tightness in the chest. Like I had smoked too many analogs.
I also had that cough back in the AM.
I thought maybe it had something to do with the mesh instead of wick, but reading the replies to you, I don't think so....
I did start DIY and my juice is heavier on the VG that the commercial juice I previously had.
I also admit to vaping more, I can taste the juice better, and it tastes darn good! LOL
Besides, it wasn't just my standard, my Ody was doing the same to me, "full" lung feeling and the cough now and then.
I just backed off the vape a little.
Odd, cartos don't do that to me, regardless of the juice I use.
Anyway, keep us posted how you're feeling!
