Protein Amts?

So I am almost 3 months out from surgery. I've only lost about 13lbs which is kind of discouraging except I know some of the reasons for that. I've got crazy bad arthritis which has hindered my exercise plan. Over the holidays I ate poorly. At least I could not eat large amts, but I definitely indulged in sweets & not-great-nutrition-choices.... I have had 2 fills & am definitely restricted & I am surprised that I haven't lost more weight w/ the small amt of food I can consume. Said all that to ask this....are you experienced banders really getting close to 100g of protein a day? I had this great plan of how I would consume protein in liquid form most of the day & add in fish/chicken/eggs, but I am really struggling. One of the nurses w/ my surgeon said 60g is good, but 100 should be my goal. I just do not see how that is possible to consume w/ the restriction I have at this time.
