My husband drinks a lot of soda at work. I'm not happy with this because of the sugar and the plastic bottles. What is the best alternative?

I make tea for him at home. I buy soda at the store for him to drink on the weekends at home. I don't want him getting soda from fast food or stores because I don't like the plastic being wasted. <br><br>What's the best soda at the store that's low sugar?<br><br>What's the best tea that's low sugar you can buy? If you make it yourself, it's quite a project to make it sweet and get it in bottles on the fridge to grab drinks and go.<br><br>Any other ideas? What do you send your husbands to work with?
