Nick33 sez! If you are looking for more realism
or you're getting ready for Fallout New Vegas Hardcore.
Then this is for you. I know there are tons of these out 
there but I can never get them to work. Adds weight to Meds.
I'll list a couple. Stimpak .5 Buffout .3 (Because it probably isn't full.
Mentants(all types) .1 Jet .2 Ultra jet .3 Phsyco .6 Med-X .2
Stimpaks and Physco are so heavy because they are metal.
