Welcome, Fifi and Congrats on the weightloss!
When you say you had blockage, was it food or did your band tighten from irritation or swelling? Also, what were your symptoms? I am curious because I haven't heard of this. I like to keep educated about the band just incase someone else demonstrates the same symptoms I can give an informed opinion on what it might be.
I am glad your surgeon is taking the fill process nice and slow. This allows adequate time for you and your band to adjust.
Look forward to following your progress!
