<p>Another Diet Coke junkie here. Actually, my real drug of choice is Tab, but its hard to find. Bone density fine so far. I like my caffeine cold, so I need a can to start my day. I’ve cut back to 2 cans a day. I buy the smaller (7.5 oz) cans now, so I’m only gulping 15 oz. day, down from 24 oz.</p>
