Really dry, cracked lips- help please!

[melbel]

vitamin B deficiency is also associated with cracked lips so maybe up your vegemite intake or swill some berocca...I find that always helps when they get really bad like that

I have tried the Blistex in the white tube so may try the Carmex or it is the same thing. I googled my issue and other sites said it was a dehydration issue but I think I drink about 1.5 litres of pure water a day in winter and about an extra litre in summer. I take my preg vitamins but may check for Vit B deficiency. If I take folic acid as part of the Blackmores supp would it be too much to also take another folic acid tab on its own as well?
Ouch about the lemon but will try also. I remember my sister telling me that it helped with cracked nipples when I was having breastfeeding issues in the first few weeks with DD so I rubbed lemon halves over them and OMG the sting!!! Never again!!
Thanks for all your advice.
