YES it does get better. I had one episode two years ago when I went to a baseball game and the whole concrete area in the bleachers was painted a ghastly red paint that just shocked my nervous system. I had to avert my eyes up into the sky to keep from feeling nauseated; fortunately I also took my ear plugs and that helped to dampen the stimuli from the noise of the game. Turned out enjoyable.

You have to gauge for yourself, and pull back/get away from the stimulation when you feel jittery or nauseated or anxious. Know that it gets better with time, but your brain is healing from a bruise and no medication in my opinion can really help with the stimulation problem. It's kind of a symptom that lets you know how well you are improving.

Be gentle with yourself. You're worth it.
