The need to keep adjusting your BCD may suggest you are carrying too much
weight on your belt.... check to see if at the end of your dive with a low
tank you can remain stationary at 15 feet [5 m] safety stop with no air in
your BCD... if you sink or need to fin to stay there take off some lead.

The above has some value, though I find that often new divers tend to extend
the pause too long by concentrating on it *only* and end up worse off than if
they had done nothing.
The key is to slow all your processes down while diving and this only comes
with time and true mental relaxation from one's internal confidence.... strive
to be the slowest diver in the pack! Then all the critters will be looking out
again just as you arrive at their space.  ;-)
Till you get to that stage Angelo, which may take you another 20 dives or so,
you can try the technique of exhaling by making a humming sound as you exhale
[the act of humming will slow down your exhalation rate and your inhalation
rate may follow too]... not too loud now as you may annoy nearby divers. :-)
