Recurrent rashes on my face with some swelling and sometimes has affected my eyes. I have tried to narrow down the trigger but nothing turns out to be accurate. It gets better then comes back. Is the certizine, a prescription? And what dose of the NAC; did you take more than it says on the bottle? Your results are very encouraging. Thank you!
