Taking frequent breaks to a quiet possibly dark area to rest your senses will greatly help your ability to be at the get together. I suggest you plan on needing the next day or two to rest and recover, even if you do not feel over-whelmed or fatigued at the event. PCS usually causes a delayed reaction to such events. Resting up before will enhance your tolerance.

I know what to expect afterwards so I can take educated risks about such events and my level of involvement. Over time, you will learn your own tolerance and risk levels.

My best to you.
