I believe that sudafed and benedryl are 2 different families of antihistamines. Many antihistamines seem to work for one person and not another, or different amounts are needed. Response to antihistamines is very individual. If it bothers your milk supply then don't use that particular family or try another avenue (someone mentioned some homeopathic remedies to use).
