Being 2.5 years in FT for HRT, and about 16 years off and on, I will say that it smooths out. BUT- focus on the internal changes, thought shifts, emotional fluctuation, and how you handle them.
Too often you see people sooooo focused on the external changes they forget about the more important internal ones. I have seen things not turn out well when the internal changes finally catch up, the worst case led to nervous breakdown and detrans. It is absolutely vital. I know it sounds repetitive, buuuuuut I think the jist of it is laid out.
But yes, focusing on them early on is also beneficial as what you get physical will blow your mind once you see around 1.5 years. Document with diary daily how you are feeling, even slightly. Its so fun to eventually sit down and look back on and think "wow, seriously" "like seriously face?" LOL. Physical Documenting is not for everyone. What is that saying? a watched boob doth not grow?
