Hi arpedkedarki
all that stuff is pretty normal...I didn't have head pressure or depersonalisation but I definitely was fuzzy and vague....
sometimes it seems to take a long time to lift - I finally felt consistently 'good' around the 3 month mark.
but when you think of it in terms of 40 years using and drinking we get off pretty lightly
Of course, if you're concerned, seeing your Dr is a pretty good way to go.
