My doc says there's no difference with the pill I take (little bluish oval)...but I started dissolving it under my tongue, got the same gooey effect you've had.
Tried as hard as I could, but there's always some that sloshes out...but after about 10 mins it's gone (probably mostly swallowed?). But I "felt" better afterwards, like it was more effective...to the point where I would do the sublingual method if time permitted.
