"15 years old, severe anxiety.  my dr. prescribed this medication for me to take on occasion when i needed it.  it worked beautifully, and i could go to dances and loud bars and restaurants again.  although it did not removed my anxiety completely, it did get rid of at least 90%, and that was enough to get me through these situations.  however, very recently i have noticed that it has stopped working and instead gives me horrible dizziness and lets my anxiety roam free.  i do take another medication for anxiety as well as another for depression.  anyhow, my gabapentin has been fought off by my body and i am going to have to switch meds again (i was on another medicine that i became immune to 4 months ago and have to switch then).  sigh."
