Strange feeling after drinking HUEL

Hi
I’ve been trying Huel in the winter and have stopped due to feeling strange after it. Now I have tried it again and the feeling is steel here. I feel strangely agitated after drinking huel, I also feel slightly nauseous. I’m not allergic to anything that I know of (and I eat everything). I tend to have some strange feeling when I drink a bit too much milk and I need to check my liver since last blood test didn’t look so good (I have bad hangovers and don’t react to well to alcohol).

Any idea what is happening here?

I think that proteins levels in Huel are pretty high if you already have issues with liver or kidneys (that’s my brother refuses to even try it)

Not really a case. I’m on a high protein diet and have no problems. My kidneys are fine.
