Yeah, I could....although the side effect from it is that it doesn't wear off, although it has already passed a month (game time) since I drank the Fortify Intelligence potions. I've also eaten some Ash Yams after that, so it'll last even longer (I've noticed that effects gained from eating alchemic ingredients are more effective and last longer in proportion to your Intelligence), so in the meantime I've even created a little lore about it:
"The great Telvanni Archmagister Brondolf has suffered a little alchemic incident while experimenting on that matter in his tower of Tel Uvirith. That indicent has accidentally given him nearly Godlike intelligence, as well as a virtually unlimited supply of Magicka. Nodoby of the Telvanni Masters (not even him) knows how long it'll last, but considering the enormous Forces he was playing with, they all coincide it could have been worse."
...besides, it just fits perfectly for a char with a base Magicka of 100 ^^
uhm...another curious effect of that insanely high intelligence is that even eating just one ingredient that fortifies something, it fortifies it INSANELY. Just eating one Moon Sugar fortified my speed for more than 200K. I ate 10 of them, and tried walking a bit....and obviously my game crashed
