Not in the "sad" way, I'm glad to say but in the last week there has been 2 occasions when i have felt cold where my fingernails have turned really blue. One was last week when i was standing outside at my mate's house and was freezin and the other was about an hour ago when i was eating a frozen chocolate tetra and feelin really cold!! How bizarre! My body temperature must go way down at these times!! Anyone else had this? Just so i know i'm not abnormal!!
