I'm in my seventh year of T and nobody ever told me they would stop. (but I have them since I was 4 years old and I'm 29 now so I'm kind of used to them (i.e. they don't bother me that much). TBH if I could pick what to change about me/my behaviour they wouldn't even make top 10- so not that big a deal for me)
As Stopdog said sometimes I get them every night (so I go few days without sleep- no point in trying) but they are times when I have no dreams or even good dreams too.

Maybe yours will stop maybe they wont but you'll learn how to live with them so it does get easier.
