I used to be highly lactose intolerant and drank a lot of soymilk if any milk at all. But since, in the past year, I've been able to rebuild and regain my lactose tolerance so now I can drink milk and eat dairy without much of a problem (heckyeaauhh).
That being said, I used to not be a big fan of milk and really love soymilk. Nowadays though, I think soymilk is alright at best. It has a very particular flavor that I only like with some things. Like cheerios for example. Soymilk is awesome with Cheerios and chocolate soymilk is rraaadd.
I've tried a lot of other lactose-milk alternatives though, and I've gotta say that my two preferred were always Lactose-Free milk and Almond Milk. Almond milk is kinda awesome, honestly. And lactose free milk actually tastes really good.
Now that I've gotta put on weight via doctor's orders though, I've found that I actually kinda like whole milk. Ovaltine also ftw. Eggnog is super freakin delicious too. But ommgg. If I didn't assume it was horrible for you, I'd drink half-and-half by the cup because it's. the. shit. It's literally so delicious I cannot even.
I still use almond milk in protein shakes though because 1.) it tastes better, and 2.) it makes the protein shakes not so uncomfortably thick and heavy. Much easier to stomach tbh.
