Could the itchy legs be an allergy to a skin care product? Body wash/shaving cream/soap? Many have sulfates in them. Although I am confused about the difference between sulfites and sulfates.
If you guys are still having issues with sulfites there is an entire group on fbook.. there is a TON of information and everyone has their own set of issues pertaining to both sulfite intolerances/allergies and other issues as well... my sulfite issues have become more manageable after joining and I've received so much information! Its a closed group with only 200 people, but well worth it to join... search sulfitesnomore (all one word) and you should be able to find it... hope this helps some of you :-)
