Hey,I get the same little twitches that I don't feel... Well I can kinda feel them if I open my mouth and see them but I think those type are enduced by holding your mouth open and using that muscle group... My main tongue twitch is right on the tip, at its worst every time I said a word ending in s or a zzzz noise it started twitching for about 10 seconds ... It kinda twitched every minute and I felt it very strong... When my anxiety was sky high I had other tongue twitches too that zapped me and jolted me... My advice as a fellow tongue twitcher is don't keep opening your mouth and looking for them as there are loads of us here ... They honestly look more like regular tongue movement rather than twitches...
