I hope you are feeling better soon.
My nails went terrible after wearing nail polish so I no longer wear anything on my nails.
Everyday I apply oil to my nails it can be any type of oil e.g almond oil, olive oil etc. I am currently using a Botanicals nail oil www.botanicals.co.uk which is nice and rich. Once a week I do a manicure starting with filing with a glass nail file, then I have an olive oil nail bath I then use a nail brush, gently buff the nails and apply oil to both my nails and hands. My nails are stronger and no longer peel.
