Certain mods like FWE or FOOK change the weight of all the aids and ingestibles.
They do have an FOSE-dependant option, but it doesn't seem to work that good. For instance on savegame-load you're over-encumbered because the script hasn't updated your inventory yet.
so you have to drop an item to manually force a refresh of the inventory data.
anyway, i guess this will be fairly easy to implement. and i can do it myself some time.
Maybe it would be best to realize with a modifying factor, like:
Modify weight of ingestibles: (x0, x0.25, x0.5, [x1], x2)
and so on.
Cheers!
