> PS. there are many other treatments that doctors may give you before reaching for the big guns; those can be very effective too.

Further, everyone reacts differently to different treatments. It's very, very common to need to try several things out (or even come back to things in different combos) to find the one that works best for you.

Heck, sometimes during the course of treatment a drug that didn't previously work for you will start working as intended.
