So, I decided to make a lot of Fortify Intelligence potions to stack the effect and make higher potions. I came out with a potion that has a very long duration. I don't really care about this, but it sort of is bothering me to an extent, but it's not like my character wasn't already capable of destroying any foe that I'd encounter anyways. Here's my problem.

I ate some ingredients that fortified my Agility and Willpower to over 80k. I did not know that Intelligence influenced the effectiveness of raw ingredients' effects, and just wanted to clear weight so I could move again as I didn't want to recall quite then.

When will these buffs end? I have done the worthless foot messenger quests of the Main Quest, as well as several writs where I would've had no different outcome regardless because I kill the target with a critical, assuming that whenever I would feel like doing some endgame content that presented a challenge (Tribunal/Bloodmoon), I would actually be challenged because the effects of at least the Agility and Willpower fortification would've worn off by then. Will this last as long as the Intelligence Fortification? I also have drain fatigue (that doesn't really do anything, but appears on debuffs with 2 pieces of rat meat listed), as well as a ton resist poison from something else (with no percentage shown, but it must be above 100).

Is there a way to debuff myself without re-setting my attributes with the console? Anyone know how any of this functions? I've been playing Morrowind for a very long time, and I've never really abused Intelligence Potions before, so I guess I probably opened Pandora's box for bugs.

Also, I have MCP 2.0 installed if that means anything as far as ways to fix it.

Someone helped me with something similar when a mod added a permanent spell effect I wanted to remove. Hopefully this will help you too.

1. Note the spell id. You might be able to find it with the UESP Wiki or for sure in the Construction Set.
2. Go to third person and open the console. Click your character and you should see Player Save Game on the header.
3. Type RemoveSpell "your spell ID"
4. Type RemoveSpellEffects "your spell ID"

Hopefully that will do the trick.

Edit: Oh, and as always, make a back up of your save before you mess with it, just in case.

Edit 2: Alternatively you could just start resting over and over for 24 hours until the spell effects end. I don't think there are any negative consequences in a vanilla game for advancing the time like that. You might have mods that are affected by time advancement though which you would have to consider. I'm pretty sure there is a console command that advances the days, but I don't know it and can't find it on the wiki list (although that list is not complete) and I'm highly suspicious that such an artificial advancement will not affect current spells.

That's what you get for "exploiting" the Alchemy system: effects and durations in 5 digits. Unless you use console commands to remove the effect, or simply wait/sleep it off for a week or whatever it takes, you're stuck with it. Be glad it doesn't leave you with a hangover afterwards.

rest/wait for 695 days eventually it should wear off (dont eat the moon sugar or skooma unless you feel like you want to teleport from Seydaneen to Tel Fyr if your intellegence is fortifying raw ingredients to 80k points .-.)
