Yes I have tried chewing gum it didn't help & took speech therapy too but with speech therapy I could not keep up because of the very hard time trying to speak with all the saliva in my mouth & that was in 2018 but in 2019 the saliva even got worse with the saliva building up in my mouth & stays there & then pours out if I don't cover my mouth with a towel or kitchen paper & trying to speak with a mouthful of water is something else. I have tried mostly because every trick there is but I know that a dilation to the ecophagus is the way. I watched the self dilation video too but don't know to get the dilator...does anyone know here in Jersey city NJ ?? I would try it since I can't get a doctor cause of the virus problem...
