Now why would you go and do that to yourself, huh?
Anyways, I'd suggest you also install Project Nevada Rebalance. It doesn't make the game a whole lot harder, just a more interesting and dynamic because it's a lot more hoard-unfriendly. I'm betting you don't want that, but well, I can't help recommending it to everybody.
I googled a whole bunch last time people asked and I couldn't find anything, and I can't find anything quick and simple now either. Try this forum:
http://www.bloodpatches.net/forum/blutpatches-32/41166-fallout-new-vegas-uncutpatch.html. I can't speak a word of german but I've noticed a guy saying "danke für den patch, funktioniert wunderbar!" which I guess means "thank you for the patch, it works wonderfully!", so there's probably something there, but I just haven't got the time to browse 40 pages for it atm.
edit: by the way, googling blood patches linked me to a lot of shady sites, but some of they might have a working patch. I just don't know how legal any of those are...
