Yes thin liquids are more challenging for me than the foods I eat. I also find thin liquids easier to consume with food. You can find swallowing exercises online. My trick to sticking with the exercises is that I always do a set when watching a sporting event on TV. It’s become a habit that way. You can tie it to any other consistent thing you do such as commuting daily on a bus, watching your first tv show of the night, etc. most exercises can be paired with eating or drinking something as well.
