I usually drink a litter of soda a day, up from 20 Oz I use to drink. I'd be hard pressed to drink a gallon but who knows the salt may make me thirty. Thanks for the heads up. My portion sizes have always been toddler size but usually 1-2x a day, now it's like every three hours. I'm worried about gaining weight but not enough to stop. Part of the reason I'm thrilled is I'm not worried about it causing me weight gain. My stomach hurt digesting it, maybe that's just in my head. I'm going to try to put salt in the lemonade to give me electrolytes. I have to change slowly because I'm known for not drinking for days if there's no mountain dew. Lemonade has 63 grams of sugar vs 77 in Mountain dew. I plan to slowly diluted it until water tastes better or I get Gatorade.
