Teethmarks on my tongue & constantly urinating.

Hi,
Any help would be greatly appreciated!
I have teethmarks around the side of my tongue and a line down the middle and I am constantly urinating.

I am trying, after an extremely traumatic past 18 months of upset and major weight gain, finally things in my life seem to be turning a corner and I feel like things are getting better. I am currently about 70lbs overwieght which is the heaviest I have ever been but I am trying to bring it down with better eating. To get myself back on track I am following a macrobiotic diet as much as possible. I also take a centrum multivitamin on an almost daily basis (some days I forget). I was thinking about taking a digestive enzyme and spirulina and wild blue-green algae but haven't bought them yet as they're kinda expensive. I drink apple cider vinegar in water a lot and drink LOTS of water and herbal teas throughout the day. I drink about 1 cup of coffee a week maximum and hardly ever have soda (I don't really like either that much). I do have a weakness for black tea with soy milk though and have about 1 cup of that a day.

I do have sugar and junk food cravings but am trying to curb these as much as possible with peppermint or chamomile tea. Plus since I've been eating a more macrobiotic diet I've gotten dull headaches in the afternoon that won't go away. At first I thought it was because I'm in front of a VDU screen at work all day but then I thought it might be because I'm eating a heck of a lot less sugar and caffeine than I used to?
The women in my family do have a history of kidney failure.
Is there anything I can do that help with the marks on my tongue and the constant urination?
