yes..i had the same thing happen..i used the revitanail system..like maria..but i did 1 coat a day for 5 days then clean off for 2. then repeat..EVERY week of chemo time and it helped a lot...altho the underbed splitting as u have described still occurred...i found i had to tape my nails down with bandaids or maybe get some of that papery tape they use in hospital-u can get it at the chemist-not quite as icky as bandaids..and kept the nail itself short..at least taped down they dont catch on things-not pretty, but at least temporary..think it took about 4-6 weeks before i didnt need to tape..and i didn't have to do every finger..
good luck with it...funny, some the things that we have to do :)
