It might be another food allergy as well. I have skin reactions to dairy, and it took me years to figure it out because a) it’s a slow reaction (6ish hours after I eat it), and b) I also assumed it was something my skin was coming into contact with
And in keeping with the OP, I also still eat dairy from time to time. Not a severe reaction, it won’t become a severe reaction, and there’s still no good replacement for actual cheese, dammit. (Daiya is close enough…sometimes…)
I use SpiralLinux (basically Debian with some tweaks). I like it a lot! If you want to stay in the Debian/*buntu lineage, consider it.
