I have a constant smell of ammonia which mostly occurs in closed in areas.  Was wondering if it's an EENT problem,  an allergy of some sort, or an adverse effect from medication.  I take an antidepressant, a statin, nsaid, a muscle relaxor, fish oil, flax seed oil, Glucosemide Chondroiten. This problem has been going on for only two months and I've been taking these meds and supplements for years.  Would appreciate any input.

  Thank You
