Am I eating too much?

I got band surgery on April 12th, so I am on pureed foods now.  Obviously I haven't had a fill yet, because it's too soon. So I don't have any restriction other than the band. Right now I can eat about 1 cup at a time....I'm wondering if I am eating too much.  This is similar to what I eat in a normal day:

Early morning - 12 oz Protein Shake
Breakfast - 6 oz Greek Yogurt
Lunch - 2 oz Tuna and  4oz cottage cheese 
Dinner - 2 Eggs with chesse

Plus fluids of course.

Is that too much?   I am just eating until I feel full, then stopping.

Thanks,
Lisa

Doesn't sound like too much to me. 
Sounds like you are doing well.

Keep up the good work!
