nymia: You don't have to study Latin alone. There are several open (and free) adult latin study groups and mailing lists. When I was brushing up my Latin 5-6 years ago, I joined a group that started with Wheelock and moved on to the Oxford Advanced Reader. I also joined a Beginning Greek group and a medieval Latin group (using the Latin Vulgate: you must read Ecclesiastes in Latin before you're through), all because it was so much fun to study with a motivated group. The group included folks from all over the world, all professionals and very nice as well as smart. Of course all that ended when life fleeced me of my disposable time :-)
I think this page represents the same community, and it looks as if they've expanded their coverage even more. I also find this page, which I think is a different group, catering more to Latin teachers. These guys have the advantage of having a group using the Oxford Latin Series, which I somewhat prefer to Wheelock.
