An Update, and Something That May Help You
First off, some back story:
I got akathisia from every antipsychotic I took until I took Vitamin D3 (prescribed). Then I still had it, but it wasn't so bad. I stopped taking the D3 every day after my levels normalized, because my primary care doctor said it wasn't needed, but I still take the gummies sometimes (maybe twice a week).
I get a shot of antipsychotic every three weeks. My mom, a nurse, gives it to me. She gives it to me because I used to get it at a clinic, and someone there messed up giving it to me, and my hip has hurt off and on in that spot ever since; it hurt for three weeks straight right after. (The nurse was fired right after giving me the shot, and I suspect there's something they're not telling me. Anyway...)
Up until two days ago, I knew this much was true: Chamomile tea helps with akathisia when I still get it. So do magnesium gummies. So did the D3, and it went away completely after I took Life Extension's Cytokine Suppress, which has mung bean (coat) extract and EGCG.
But the Cytokine Suppress made my hip hurt more, where I got the funky shot. I was scared there was some sort of an infection in there that I needed extra ooomph in my immune system for. So after two weeks of taking it, I stopped the Cytokine Suppress.
Five days ago, my mom gave me the shot.
Four days ago, my akathisia was back, almost (but not quite) to levels like I used to get before the D3. I was pacing, I was sitting and rocking, you know the drill. I took some leftover liver detox pills that I had every day for a couple of days, but they didn't seem to help. I think either I was low on D3, or the Cytokine Suppress had worn off, and/or something happened when my mom gave me the shot.
I was broke. Two days ago, when I could afford the magnesium gummies again, I took four. Then I took four more, reaching the upper limit of what they say people can take daily of magnesium. And the akathisia was still there. Full force.
I had some chamomile tea. It helped a little. But it was a bad night.
Desperate, I took a Cytokine Suppress pill. It had taken weeks to work before, but I figured one pill wouldn't hurt. And for the heck of it, I took a couple of Nature's Truth Turmeric, Curcumin, and Ginger gummies, because they made me dizzy the last time I took them and it was late at night at this point and I wanted to SLEEP.
They didn't make me dizzy, but I did eventually fall asleep. And, when I woke up, the akathisia was gone. I feel a twinge occasionally, but it hasn't come back.
I don't know what did it, but the only things I did differently were the Nature's Truth gummies (which did NOT make me dizzy this time), the Cytokine Suppress, the chamomile, and I guess the magnesium. So I'm posting this here because, well, I want to see if someone else who is desperate gets the same result. Do NOT take eight magnesium gummies, they've been making me pee every 30 minutes for the past day or so, which can happen with high doses. I don't think it was them that helped anyway, because when they helped before it was immediate, and I'm pretty sure they never made it go away completely, and certainly not that dramatically.
TL;DR: Akathisia came back. One pill of Cytokine Suppress, chamomile tea, magnesium gummies, and Nature's Truth turmeric, curcumin and ginger gummies made it go away when I could afford to take them after days of (almost) torture. Some combination of those might help you. Try it without the magnesium first.
