It looks liek you have a very nice result fromyour surgery and while a lot of swelling may have gone away, there is probably still some more there. Give it more time.
Overall you have a very nice result
with excellent contour and breast shape. This is a very large surgery and I
would expect you to have ups and downs initially, but by 2 months, you should
be close to baseline strength. Having said that, areas that are treated with
liposuction can take a number of months recover as those nerves get fairly
irritated during the procedure and nausea may be your manifestation of the
discomfort. Are you still wearing your garment? A comfortable yet firm
supportive garment may be helpful in making you more comfortable for the next
couple of months. I am not sure what to say about your weight, except for
emphasizing the importance of a continued healthy diet and exercise to maximize
the benefits of your surgery. Hang in there, be patient and you will
progressively get back to feeling yourself again.
