Was this too much or am I still ok?

Good advice from cmriverside, as always.

I'd add: Stepping back to the big picture, I'm concerned that you're possibly going at this in an absolutist and anxious way.

Instead, consider treating the first weeks of calorie counting as a sort of fun, productive science fair experiment . . . a learning phase.

The goal is to find a way to eat at reduced calories, eventually at calories below the number you burn daily in all ways, while staying mostly full, sufficiently energetic, ideally reasonably well-nourished, and generally happy with your eating routine. That will take some experimenting. Experiments don't always succeed. We learn from them, adjust, and go on.

When the plan hits a bump, like eating 1000 calories of chicken and fettuccine at 2AM, that's not a failure you need to make up for today by depriving yourself, as if at were a sin you needed to expiate by suffering. (For one, that will tend to set you up for another late night cravings-fest, I suspect.)

But mostly, it's a learning experience, and the ideal response IMO is to think about why it happened, and how you can adjust your plan to avoid repeats. Even with that, don't obsess for hours, just give it 10 minutes or so.

Did you set calories too low to start? Did you switch to foods that are less filling for you? Is your eating schedule not ideal for you? Are you one of those people who can't sleep if hungry, so it would be better to eat dinner later or have a planned evening snack? Etc.

Revise your plan, and test drive it. Adjust again when necessary. Keep going like that, and you'll gradually dial in a calorie-appropriate routine that's easier for you to stick with, without it being a melodrama about good and evil, or about being "good" vs. personal failure. It's just about finding personally workable new habits we can stick with long enough to lose the total amount of weight we want to lose . . . and then ideally stay there long term, even forever.

As far as the rest of the day, the general rule I'd suggest is just to go back to your usual plan ASAP. That's not "make up for it", it's eating the healthy breakfast, lunch, dinner and snacks you have in your general plan (perhaps adjusted somewhat to avoid a repeat of 2AM cravings and over-eating).

Maybe that general approach is not right for you, I don't know. But the low-drama, "revise the plan and go on" approach is what got me to a healthy weight for the first time in around 30 years, and has kept me there for 8+ years since. Just an option to consider, for anyone else.

Regardless of what you decide, I'm wishing you success: The results are worth the effort!
