I do drink lots of water; it is particle all i drink. I drink no soda at all. My diet consists of very little meat none of it red. I have fibromyalgia, hypothyroidism, psorisis and psoratic arthritis, plus c.r.p.s. In my l foot and bursitis in my shoulders. My feet have been a problem ever since i was a child. I have always gotten cramps in my toes and had tough feet. I hardly ever wear shoes as they hurt my feet. I use loation either no mineral oil but my hands and feet seem to always stay dry and crack around the nails ( family problem). My nails have become weak on my hands since my hypothyroidism they have always peeled. I have vertical lines in my nails with slightly pronounced rigs. The moon on my nail bed is small but well formed . The nails themselves are a healthy pink color no blue or yellowish Discoloration, slightly pitted but that is psoratic arthritis.
