When you hit those mental walls, what do you do ? I find I need to completely change course and even take a short nap. Closing my eyes for a few minutes helps.

Driving can be stressful, especially if you have rough roads. I can see how a hug would cause enough quick movement to cause symptoms.

You need to learn your triggers and how to moderate them. Many of us use ear plugs to reduce auditory stimulation. I like the yellow foam ones. I al ways have them available. I use them in restaurants unless I can find a quiet both.

For me, the intense sounds at movie theaters can be a problem. Ear plugs again and being selective about what movies.

Your physicians opinions are worthless. You have to discover your tolerances. Nobody knows how your brain and body reacts but you. Keep in mind that is not uncommon for a delay before symptoms return. You can have a great day and feel great at bed time then wake up and have a miserable day the next day. Plus, quality of sleep can predicate the quality of day. Cognitive stresses one day can show up as fatigue the next day.

Have you noticed your triggers ?
