Thanks very much for the advice,
I did try to relax and minimize my tounge movement (& specialy tried to avoid any contact with lips) in last night and todays exercise and voila', it looks like there is finaly some improvement,
and well, as silly as it sounds i never thought about the actual direction of the tounge and where it lands/takes off from, i have already started experimenting with this & i'm hoping to find out which one works best for me. a pretty exciting task actualy
Appreciativelyyyy R.
