i was kinda in the same position. 2-3 years in. i couldnt concentrate one bit, i showed up to work every day and did almost nothing. It's kinda a long time ago and i dont really remember how that episode ended. I think i slowly got back into it.

But even now, 6 years later. I still have days/weeks where im not motivated at all. And i have had periods where i worked 18 hours a day with full joy. I cant really put my finger on it. I dont know what causes this. I havent really looked into it tbh. Even though i should, because when im lazy, i feel really bad about it.

I recently had this problem again, im looking into it now. Im experimenting with quitting caffeine. quitting endless internet content. Maybe exercise. I dont think its food related. Anyway, it's to soon for me to tell, i wish i had tried to fix this earlier, so i could give u an answer.

Thank you for making this post, curious what others will say.
