Plugged Ducts/Lecithin

I've been having issues with severely plugged ducts. I only have one duct on each side that works. My lactation consultant recommended Lecithin for the duct issue and Fenugreek to boost my milk supply. Have any of you had any luck with either of these? It's very important that I don't lose my milk supply. My baby has been in intensive care since she was born almost a month ago, and my milk supply has been dwindling for the past few days since she was transferred to a hospital farther away. Thanks for your input and/or advice.
