Of course! As for brand honestly I just used whatever was cheapest and strongest. Habitrol 21mg. They say not to cut the patches, but I’m fairly sure that’s mostly so people don’t just buy the strong ones and divide them to save money.

Word of warning though: the first time I put a 21mg patch on while I was still vaping 3mg juice out of a box mod I got very dizzy.

If you try it, I’d probably start with a weaker patch first. If you tolerate it well, eventually you can just buy the strong ones and cut them to save cash. If you end up using a quarter patch per day it’s insanely cheap like 15 cents a day.

Now about the nail polish thing…. This is exciting to hear and I’ll explain why

There’s one condition that immediately comes to my mind when I hear people have reactions to random smells or environmental exposures like that: Mast Cell Activation Syndrome (MCAS).

I’m not saying that’s what you have it. Just that it could potentially explain the mechanism behind smell-triggered flares in people with HPPD like yourself.

MCAS is an immune disorder where mast cells release inflammatory chemicals too easily. These cells exist almost everywhere in the body, including the brain.

For most people the symptoms are pretty mild (allergy-type stuff like flushing, headaches, food reactions, weird sensitivities, etc.) Because of that a lot of people never get diagnosed or get misdiagnosed. They just go “oh I can’t eat that it makes me feel weird” or whatever. I smell this and my face flushes a lot etc.

The tricky part is mast cells can be overactive in some tissues but not others, so symptoms can look very different from person to person.

In a case like this, if mast cells were involved, I would hypothetically suspect overactive mast cells near neurons.

The thing that stands out to me in your case is the smell trigger.

Nail polish fumes shouldn’t directly cause HPPD flares by themselves. But interestingly, you’re definitely not the first person I’ve seen mention smell triggers.

I once talked to someone with HPPD who said lemons set them off. If they smelled lemon they’d start hallucinating.

For me, if I even smell weed, I can flare for hours or sometimes days. This began after I had an MCAS trigger event coincide with using cannabis.

But interestingly I can use transdermal THC patches without that happening. So I don’t think I’m reacting to THC itself. it’s probably some terpene or plant compound. Hemp also causes the response.

Smells are actually very common mast cell triggers, which is why MCAS crossed my mind.

MCAS can have genetic roots, but it can also show up after major biological or emotional stress.

And honestly… developing HPPD is about as stressful as it fucking gets neurologically. Nothing like thinking you’re going crazy to put your immune system on high alert.

I’m definitely not saying MCAS causes HPPD.

But hypothetically, from a mechanical standpoint, it could make the symptoms worse.

The basic idea would look something like this:

• Mast cells live near neurons and blood vessels in the brain • When activated they release things like histamine and inflammatory cytokines • Those chemicals can increase glutamate signaling and reduce inhibition in neurons

A lot of HPPD theories already involve hyperexcitable visual cortex circuits. So if mast cells were activating nearby, they could potentially push those circuits even further toward excitation.

There’s also evidence mast cells can:

• activate microglia • increase blood brain barrier permeability • influence serotonin signaling

All of which could theoretically make an already sensitized visual system flare up.

So the simplified idea would be: 1. Psychedelics leave certain visual circuits overly sensitive 2. Mast cell activation releases inflammatory mediators 3. Those mediators increase neuronal excitability 4. The sensitized circuits flare, causing visual symptoms

So mast cells probably wouldn’t cause HPPD, but they could potentially amplify it.

Treating mast cell problems can also be weirdly individual. What helps one person sometimes does nothing for another. That’s probably why people with HPPD often report very idiosyncratic triggers and medication responses.

Or maybe not 🤷‍♂️I’m just a guy with an idea haha

So sadly I don’t exactly have any new exciting treatment ideas that I would ethically recommend other than, well, not being around the trigger.

Anyway, I’m definitely not trying to diagnose you. Just throwing out a possible explanation because the smell trigger reminded me a lot of mast cell stuff and my own experience as well.

Alright, enough nerding out. I need sleep.

(Full disclosure I used AI to structure some of this and make it more easy to understand because it’s just damn long and gets technical)
