Oh I want a dr pepper can I have dr pepper I know I can't have pepsi

same thing, you can have both. it's idea to avoid caffeine so root beer and ginger ale are your safest bets but you're allowed to have 200mg a day of caffeine it's not unsafe, you can still drink a cup of coffee if you wanted. but soda has such little caffeine anyway you're fine if you have one or two it's just unhealthy obviously lol.
