I would definitely check you diet and routine. What I felt was a mass load of food when I started eating healthy was actually only about 2000 calories. And that's a pretty decent cut for me. And lifting as heavy as I can but learning to focus my muscles rather than just getting the weight up changed everything quite a bit.
Look into other protein too. There is no reason it should be hard to get down with the products out there. I prefer Optimum Nutrition brand protein because it is manufactured well and the taste is decent. Anyone should be able to drink that shit all day easily. And since you are naturally skinny, you could always go with BSN products. Not as healthy but jesus, their bananas and cream shakes are fucking amazing. But you should get as much protein from natural sources. Just use shakes to cut down on how much food you need to prep.
Lastly, and I'm not recommending this and never would. But when I started out at 19 @160 pounds, 6 feet tall, I fell into the notion that you need to eat big to get big. Well, I sure as hell did. Lol I was eating 3 double bacon cheeseburgers with fries, tons of water and 3-4 scoop shakes a day. Now this is a HORRIBLE way to bulk. But it got my body easily use to eating lots of food and always stuffing myself because it tasted good. In a little less than a year I was 220 and lifting real heavy. Needless to say, I was about 25% body fat in the end. Lol but I got big!
In the end it made my craving way worse than I think the average person gets when I switched to eating clean. But I can also down ridiculous amounts of food because I was use to it. Again, I wouldn't recommend it in anyway but it is a route you can take if you just can't possibly eat anymore...
