Coughing and wheezing 3 weeks after getting sick, Please help

I was on round 7 of andy cutler mercury detox with DMSA, I got sick at the end so I stopped the round. It has been 3 weeks and I still have a bad cough and wheezing. I took antiobiotics for 7 days in hopes to get rid of this. I hate antibiotics but only take them when I have to. The antibiotics did absolutely NOTHING! I eat a gluten free diet and dont touch anything processed. I am a 31 year old male and have never been sick for this long. What do I do to clear this up. I have sever wheezing and coughing up lots of phlegm. HELP ME! Tweet
