Time to die-t

Eating 10,000 health worth of food is not only dull but tedious.
To get the achievement I had to go to a food vendor, buy out all their stock, then wait 3 days in game time (sped up) until they restock till I could do it again. after doing this a dozen times I would drown my character to 1 HP and eat all the food, only to find out that it was not enough and I had to do it all again.

after doing this process 3 times and eating a metric ton of food (odd the my character's weight didn't increase), I finally got the achievement. Tomorrow I'll load from before this mess and go for one of the weapon achievements.
