Thanks for your response.

When I get dizzy spells, they usually last for 15 minutes or more. Basically till i take it easy and sit down for a bit. Its not a spinning sensation like vertigo. Its more of a everything is rocking a bit like being on a boat type vision. Off balance. Poor equilibrium.

The causes:
The things that cause dizziness right now are being in busy ambient places like walking through a grocery store. Walking through my condo hallway (with the patterns on the carpet). Driving. Talking to people in busy ambient places (like stores)

I have read about the epley maneouver. I thought this was only for vertigo from BPPV. I never came upon any articles that said the Epley would work for non vertigo type dizziness that i have. Do you know if this is correct?

I'm going to give this a shot. If i experience any dizziness, I am going to try and not to dwell on it too much. I am going to try and compose myself and let it pass. My personality is that I get too hung up on things. I'm basically trying to notice any symptoms I may have. And I'm really bad at handling setbacks. My brain works best with linear experiences. So I may not be the best at handling PCS. But I guess I have no choice. I'm going to have to program my mind to not get too caught up on every little symptom that arises.

Thank you for your responses. You've been really helpful with your knowledge.

I bet your problem is:
First, Over-stimulation. This sets off a mini-anxiety issue.
Second, You pay attention to this little struggle it and it magnifies.

The triggers are
Visual stimulation.
Bold patterns on the carpet
Signs and other visual stimulation in stores, A shelf with hundreds
of products ate eye level
When driving, objects moving around you

Sound stimulation
Too many voices talking too you. (your talking is only a problem if
others talk over you, in most cases)
Ambient sounds that are common is stores
Echos, a problem in larger buildings, malls etc.
The PCS brain hear echos that the non-PCS brain easily ignores

The brain naturally wants to make sense of our surroundings and stimulation. But, it usually can filter out the vast majority of sensory stimulation. The PCS brain does not do this well so all of the sensory stimulation is processed, or at least the brain tries to process all of it, and CRASH, the brain overloads and systems start failing.

For people with Type A personalities or higher levels of observation skills or intelligence, this is more of a problem. As you said, you process in a linear fashion.

But, PCS makes it so the brain does a lousy job of sorting and organizing so it gets hit with this abstract pile of chaos.

We can choose to ignore it. It is a challenge but the simple explanation is that we need to learn to pick our battles. The pattern on the carpet is not a worthwhile battle. Try to avoid looking at it. The sounds around us can be reduced with ear plugs. Mack's makes good ones. Carry them everywhere you go.

Socializing needs to be moderated by not getting involved in group discussions unless everyone can learn to not talk over each other. Even then, sounds coming from the sides can be a struggle. It is easiest when you can look directly at the person who is talking.

In a restaurant, try to sit near a wall or corner (best). This limits the angles the sounds are coming from. I have to do this or wear ear plugs. Sometimes both in a noisy restaurant.

Driving is a challenge. I do best without the radio on. No or minimal talking. Avoid busy times if you can.

And, try to let go. Pick your battles. PCS makes the world too abstract so we have to make an effort to ignore much of the chaos.

It is a challenge that we can win once we know the system.

btw, Your dizziness does not sound like a vestibular issue, nor a movement induced issue. The Epley is for movement induced dizziness.
I have movement induced struggles. I can only make major movements on one plane at a time. Lean forward in my chair, pause for a second, then stand up. I can't do them both in the same movement.

Hope this helps.

My best to you.

Thanks for the long write up of how to work with my issues.

Can you expand a little bit more on what exactly"movement induced issue" is?

Some other dizziness triggers i forgot to mention:
I do feel dizzy/lightheaded for a few moments when i'm lying down and then i stand up. Or sitting down and stand up too.

I also feel dizzy if my head turns/moves quickly sometimes. (like in the shower or brushing my teeth)

And sometimes when i'm lying down on my back, and i'm looking in a perticular direction, my head feels weird. (little nauseous)

These are movement induced issues. You move and it triggers a dizzy response. The getting up from laying down or sitting can be blood pressure oriented or inner ear. The other movements suggest possibly inner ear/ Epley treatable issues.
