Hey man!
Your situation... well, it sucks

.
I know this, because I am going through something kind of equivalent.
Whenever i burn, I end up feeling sick as all hell, and .. well, just really weird.
I haven't gone to a doctor or anything, and I definitely don't want to take a t-break
So I tried a couple things that seemed to work. (by the way, I am also extremely stressed with family / life right now )
Firstly : Try a different strain of weed! Certain strains effect the body differently, which can fuck you up.. I did this, and it worked to an extent, but not while I was alone.
That brings me to my next point. MAKE SURE you are in a good environment. Personally, when I am alone and I bunn, it just lets me think about all of the shit that stresses me out, and i REALLY focus on it. Shit, that's the worst. "getting lost inside your own head" Next time you smoke, make sure you are with people who you KNOW you will have a good time with! It's pretty important.
Btw! You might be getting sick just because you are used to it! I mean, I'm not shutting down anything else, mold, stress, all of that stuff are great causes to make you sick.. I'm just making my own suggestion. I don;t know about you.. but when i'm high , I think about times in the past when I was high, and kind of relate them sometimes? So if I have a "bad trip" so to speak, I keep on having it over and over just because I start thinking about it and get worried about it. If you have a really good time with friends / etc. it might help out a lot!
try a combination of new weed (new strain) AND good times with friends! see what it does for you! haha, it worked for me

One last thing : If none of that works/.... Try out a vaporizer. Maybe it has something to do with the smoke? Good ones are pretty pricey.. so you can maybe go to a smoking cafe and try one out. (we have the Hotbox Cafe here in toronto)
- On a side note! Good luck man! I'm sure you'll get better. The herb can't get you down forever, it's just against the rules!
Let me know the outcome!
