I am a wizard in the first town, and the food is used up, there are no food spells to be found, or rats around to eat, and I am dying and can't heal properly !!! Not even the barkeep has food

I feel the game is a bit broken like this... Still love it though, is there something I should know? Like an everlasting apple tree or something?
Also, I chose to pursue heavy armour with my wizard and got the skill in character generation. I then had the thought, that there might not be many heavy armours in the game which complement a wizards skills !!!...Is this the case? Or should I restart and choose light armour instead...
Bah, I have already restarted 2 times :p Where can you find a food scroll ? I have tried re-searching a chest over and over hoping to strike lucky but no cigar... im still starving :/
