I’m one day in advance with all my desks and the number of cards to review is getting larger and larger.
This happens because the intervals after reviewing ahead are shorter than when you do the regular study.
Whenever my response is correct I click on the “easy” button, but the intervals of the cards that have been recently reviewed are still short. So the amount of cards to review each day keeps growing.
How can I fix this?
Thank you.
When you study ahead you are messing with the algorithm already. Thats not how this works
If you want to reduce load when you have the time, study ahead only cards with big intervals. For example, study cards that are due in the next 10 days with prop:ivl>200d
Messing with cards that are new is going to have a bigger impact and the algorithm is “punishing” for that
1d ahead of time is going to have a big impact when your ivl=3d, but its going go be barely noticeable in a card with ivl=365d
With this idea in mind, create your own study ahead filtered decks that have minimum impact. It depends how old is your deck
I was able to generate double my study load when i had time with minimal impact on the algorithm or following week load and i was literally reducing next 10 days load (or incresing it if you fail a lot, but you were gonna fail those cards when due any way)
So, I create the custom study session 1d ahead.
Then I go into Options. I select the cards by “decreasing intervals” limiting to the number I want to revise (70 to 100 in my case).
Tick “reschedule” and Rebuild.
I have now the chosen number of cards, ordered by intervals.
I made it with my first deck and it looks good. I’ll see what I find tomorrow.
Now with the second deck, I created the custom study session 2d ahead with the same setting.
Yes, I think I am going to use this with my oldest decks.
Thank you.
The entire question is why are you reviewing ahead at all? Reviewing ahead isn’t supposed to be the main way you study (what @ whatchu said), instead you should study as the cards are given to you (that is mainly the point of the software).
I guess this is so. But considering the days I have no time to complete the task, I prevent myself from falling behind this way.
Today some decks are already up to date since yesterday I didn’t find time to review in advance. And this is the customary.
Thank you.
The main reason anybody has to review ahead is that you have completed today session and you still have time and energy for more 
There are ways to double the load of the day and help you reduce your future load with minimal impact in the algorithm
In my opinion, it’s much better to do filtered deck reviews without rescheduling in that case. It effectively tests on how well you remember the material and I believe that it doesn’t affect the scheduler much (I might be wrong, I don’t know much about the scheduler).
I don’t think that’s correct. If the goal is to take care of some of the Review cards and lighten your future workload – studying with reschedule-based-on disabled would defeat the purpose.
@whatchu 's suggestion about choosing the cards that will have the least impact on their scheduling is a good way to go. “Decreasing intervals” is exactly how I used to do this back in the pre-FSRS days.
But another method is to use the FSRS Helper add-on to “Advance” cards, and let it do that choosing for you. https://ankiweb.net/shared/info/759844606
Or if the days you when you have more/less study-time available are consistent week-to-week, using Easy Days in Deck Options is another approach. Deck Options - Anki Manual
