Yeah I can't have Ensure, I remember when I had it, my tummy really swelled up and I was in tremendous pain
. I was very upset because the flavors were delicious!
If you want to gain weight there's loads you can do to help. You could start adding more delicous oils to your diet, I use a lot of Hemp oil, avocado oil, flaxseed oil, olive oil and cocnut oil.
Also have you tried very very dark chcolate? It is what I would call a superfood, very nourishing and it'll definitely help with weight I think.
Avocados are very rich as well, I love them
.
There also a lot of protei drinks which are fantastic and lactose free, such as Hemp proteins, some whey proteins and soya proteins, I think you can even get flaxseed proteins as well!
Good look xxx
