I have not had an adjustment in 5 months and I have not lost weight either. I thought the band was too tight because I frequently could not swallow my own saliva after I ate until I threw up a lump of mucus. I was recently told to use Mucinex to get rid of the mucus. This helped. Now I think I should get the band tightened so I can lose weight. I can't decide if it is too tight or too loose. Anyone else having the mucus problem?
