Rebif & Antibodies

Hi, saw my neurologist today who said that they are going to check my bloods as it seems I am starting to build up antibodies to Rebif which I have been on for 3 years. He did say that I might be switched to another treatment if it continues to rise. Am now panicking as whilst I have only been taking medication for 3 years it seems to be working and I have had no relapses, has anyone else had the same problem? and is there anything I can do to lessen the antibodies rising - even if it means giving up the Wine!
