Awesome! Congratulations!
Do you have any idea on your body fat % when you started? If so, you can figure out your approximate TDEE. For instance, according to my last Skulpt scan, I'm approximately 16% body fat at 187 lbs. My TDEE should be roughly 2100 calories. That's essentially what I could eat daily without exercise and not gain fat/weight (i.e. maintenance calories).
