So glad you're back!
You can have the excess skin removed but it's difficult to get it done and it really depends on your PCT. But they usually won't do it until you've hit goal AND maintained for a year. Otherwise, in their mind, they could spend that money doing something that's generally pretty cosmetic and then you go right back to how you were before, wasting their money. It's understandable I guess, annoying but understandable. So it's worth asking about it but it is more difficult to get done unless it's that bad that it causes problems like infections and stuff.
Have every faith in you to get back on track, welcome back!
