I am in the same boat as you. I just had my second son and I was diagonsed with PTC 4 years before the birth of my first son. I haven't taken my meds at all due to the symptoms being gone for both pregnancies. I am now suffering horribly. I developed an allergy to sulfa drugs after my first pregnancy. now I discover that diamox is sulfa based! CRAP!! Now what? my docs think I am crazy it is so frustrating. I have horrible insurance too.
