No Survival Diseases

If you'd prefer to have more options/control over the duration of diseases instead of getting rid of them completely, try Survival Disease Immunity.

This mod expands upon that mod a little further and removes items like Antibiotics and herbal suppressors from leveled lists and vendors since they're made obsolete by this mod (you can still craft them, however, but like I said you don't really need them so they're ultimately useless).

This is a mod I made for myself after realizing how poorly integrated diseases are in Survival. They're as easy to get as they are to cure, especially when you acquire the ability to craft Antibiotics yourself (made with such common items, nonetheless). Get an infection from getting scratched by a ghoul? Just pop an Antibiotic in there and it's gone. Lethargy? Antibiotic. Parasites? Antibiotic. Super Cancer? Antibiotic.

This mod doesn't aim to improve this system at all, rather offers an alternative for people who just want a simple Survival experience where you must frequently tend to your primary needs without getting an arbitrary debuff every couple of minutes.

Additionally, there's 2 things this mod doesn't make you immune to: Vault 81's Molerat Disease (there's already plenty of mods for that), and the Dark Craving addiction you get from eating corpses with the Cannibal perk (which could not be cured by Antibiotics). This mod also suppresses any messages related to acquiring these diseases, so it's like they were never there at all.
