Why do you need to cheat? (I assume from the sad smiley that you ran into a problem)
If you encountered a tough opponent, scorpion traps are quite over-powered, as are weapons with Frost on them. Enough 
restoration potions can get you through pretty much anything. Hit and run tactics with a bow are very effective, though can be a bit tedious on really strong enemies.

ways to cheat;
iZakaroN's SaveEditor (or from 
Kiya's site, with description, which also contains DAD's Item Editor)
Lost Items - guide and directory of inventory filesTeleporting Anywhere, via hex editorTo copy an item; quick save the game, then drag an item out of your inventory, but not somewhere there is a red X.  Without dropping first, quick load the game, then release the mouse button when it starts to load.  This will produce a copy of the item on the ground, with the original still in your inventory.
There is a much easier method for items which can be stacked;
Drag a stack out of (or into) your inventory (or container) and hold down the control key before dropping.  This will bring up the split stack pane; type in a negative number and hit enter (the checkmark will be greyed out).  This can also be done in the trade window.
