Whatever flying you have done in the past does indeed count toward the 45 minimum hours. It will also mean that you know what you're up against (providing it was not just a 20 minute so called trial lesson). Unless you can train in less than 6 to 9 months you're likely to take 50 or 60 hours to get to licence issue anyway, but you will remember some of what you did before which should help. You obviously still have the desire otherwise you wouldn't have posted.
How many hours did you do?
(P.M. if you prefer)
