Starting FML on Monday, what to expect?

[Manupi]

I'm starting FML on Monday and honestly I don't know what to expect. I've read that many (if not most) people improve only and during the treatment, but go back to "normal" (i.e., the usual dry eyes pain and nuisances) soon after leaving it. Has anyone had good results with FML? And by good results I mean lasting, mid or long term results.
I'm not very optimistic about it, honestly
