I've been vegan for over six years now, but I stopped with dairy products about six months before I went vegan. I used to get throat infections all the time, and my then-girlfriend (and now-wife) insisted it was because of dairy. I brought this up with a doctor, and he shocked me by saying it was probably true, at least in my case.
Since I went dairy-free, I've had:
- soy milk (never liked it much, since I always felt a bit off after having it)
- hemp milk (something about the texture grosses me out)
- almond milk (meh - I don't love it, but I'll tolerate it)
- rice milk (alright, if a bit watery)
- oat milk (better than you'd think)
- flax milk (my current favourite)
I really want to try hazelnut milk, but I don't think I've ever seen it for sale.
