When someone is diagnosed as a lactose intolerant, at first it can be quite difficult. For example, what do you put in your coffee if you cannot put milk? Sometimes that is all there is regular milk.
However, what I have found, is that Starbucks really offers a great selection. They have soy milk, coconut milk and almond milk. Generally, all of these can be found at the station where the other milk products are. If not, just ask!
Another thing I love about Starbucks is that all of their milk based products, whether it be a latte or a frappuccino, can be made with a milk substitute. While there is a small up charge for it (60 cents at my local stop), it makes the transition a lot easier. My go-to drink would always be a vanilla latte. When I found out I could not have dairy anymore, I was quite concerned, to say the least! Now, I can enjoy my drink safely, and happily!
