Have you tried anti-anxiety meds before? (Do you also deal with depression, anxiety, etc)?
Felt different when modifiing diets?
I'm lucky that no real depression or anxiety that I'm aware of. Well, I used to get kinda stressed before flights - hated airport security hassles. Fine once I was on the plane. When I flew frequently (many years ago), I used to take 2.5mg Valium maybe once a month. Pretty minimal. I've tried it recently (old prescription but pro'ly fine). Helps with some muscular pain and tightness, but don't think anything else.
I've tried a bunch of stuff - nothing helped much. Diets from carnivore to keto to AIP to low-histamine to low glutamate to vegetarian to vegan to Wahl's. I haven't tried vegan or Wahl's in a few years now that I think about it. Also did some fasting which I found made me feel crappy, but also maybe helped a bit? Hard to say.
Haven't really explored stimulants (dangerous I believe for crashing, but I may try at some point). Beta blockers didn't help. Ashwagandha, quercetin, vitamin C, BCAA, Q10, creatine, Cialis, LDN, Valium, uridine, d-ribose, xylitol, black seed oil, theanine, naphazoline, tongkat ali, kudzu, testosterone, Chinese skullcap, knotweed, ACV, selenium, NAG, passion flower, lycopene, magnesium, methyl B, cumin, curcumin, saffron, taurine, forskolin, fisetin, EGCG, chlorella, monolaurin, allicin, cat's claw, andrographis, beta glucans, reishi, ku shen.
Just skimming through my list of recent supplements. Feel free to ask about anything specific.
