Hang on, how have you gone from barely being able to stomach 1000 cals per day to eating nearly 3000?

Do you know what your TDEE is? How big are you now, male/female, activity levels etc?

What exactly are you eating, and when? How long have you been eating nearly 3000 cals per day, and what does 'nearly 3000' actually mean? 2950, 2650...? All of this makes a difference.
