on the teeth front...diet coke is MUCH worse than normal coke, has higher acidity than normal coke
you think?? I would have thought both coke and diet coke have the same acidity - if not coke having more. I think that stuff could strip paint
And coke has the added evil of pure sugar which does not help anybody's teeth.

Again, with comparison to me & my DH... my teeth are as strong as nails... where as my hubby's are in shocking condition - needing 4 root canals recently.

As I said before, I think that weightloss helps conception more than not drinking particular beverages.
And when it comes to weight loss - water is the optimum drink - but I just can't stomach water...
Diet coke is better then coke (for weight loss)... and 1-2 glasses a day is nothing to worry about. Even in the "what to expect..." book they said that 'excessive' coke drinking was MORE THAN 1 litre a day! So I wouldn't panic too much with 1-2 glasses a day.

BTW... do you drink coffee as well??
I wonder if excess caffeine has any effect on conception?
