How to unlock the I'm an Addict achievement in DeathSpank - Definitive Guide
Two ways to do this, quickly and as you go.
If you play anything like I do, you will pick this up before you end the game, simply from healing yourself.
The quick way is to keep buying potions from the Ex-Orphan Vendor who is located to the west of Bob the Fisherman and north of Greem Lake. She's along the path right at the end of the bridge after Bob. I believe you have to do a quest for her before she'll start selling potions to you. Finish up what she wants you to do, then buy potions from her. If you need money, just travel south along the path towards Greem Lake. Tons of stuff to kill and loot. Keep repeating until the achievement pops.
Really though, you'll get this going through.
This will probably come over the course of playing. Just make sure to keep drinking potions when you need a health kick quickly or at random if you are just going to complete the 50 needed for the trophy. Potions can be bought, obtained from chests, given after the completion of a side quest or dropped by enemies after you kill them. After your 50th one taken, the trophy will pop.
Since you will get hurt a lot, even on easy, this achievement will come naturally as you progress. Instead of eating any food stuffs to replenish your health, use the health potions (the red bottles) to heal yourself. It doesn't matter what size they are, as long as you drink 50 of them. If you can't find enough through exploring the world, you can buy them at the General Store in Pluckmuckel, which is the first major town you go to. It's to the north of your starting location and you reach it after the Demon Mines.
