Seeking Advice on Adding Rexulti or Fluvoxamine for Mood Stabilization with CFS/ME/Long COVID

Hello everyone,

I've been grappling with CFS/ME and long COVID since 2019, which has severely impacted my daily functioning due to persistent brain fog and fatigue. See my other post [here](https://forums.phoenixrising.me/threads/advice-i-am-seeing-a-psychiatrist-and-a-cardiologist-what-should-i-suggest-to-them-to-ease-my-brain-fog-and-fatigue.92519/).

Currently, I'm on a regimen that includes mirtazapine (7.5 mg) and trazodone (50 mg) which were prescribed since 2021 for sleeping purposes. Previously, I have also taken Lyrica from 2021 to 2023 and was on SSRIs for almost a decade until stopping them in 2021.

Lately, I've noticed that my mood has been increasingly affected, which might be worsening my cognitive symptoms. I've been reading about Rexulti (an Abilify variant) and fluvoxamine, and both seem promising in different aspects. I am considering adding one of them to my treatment plan but am unsure which might be more beneficial given my complex health history.

I would really appreciate insights from a pharmacology standpoint with these medications, in fact, I am already on Rexulti for 2 days and would say that mood has been slightly better, but brain fog maybe reduced by 20% (say from 7/10 to 6/10 severity in terms of sensory overload). I am just struggling to figure which should I experiment first since psy medicines are notoriously hard to taper off and I do not want to get the order wrong.

A change to the title: Seeking Advice on Adding Rexulti or Fluvoxamine for Mood Stabilization/Brain Fog with CFS/ME/Long COVID

And a bit of addendum, I have been on stimulants such as ritalin from 2021 to about 2024 May, I tapered it off in May 2024, this may be a bad decision as when I try to go back on it (I relapsed badly due to PEM), it _worsened_ my brain fog, this is paradoxical, and doctors are confused. So the stimulants route seemed to not work for my brain fog anymore, sadly...I was not even on a high dose to begin with.

I'm not a doctor, so feel free to ignore my advice, but I'm just going to share my experience.
When I got sick with CFS, doctors kept putting me on different SSRIs, I tried literally a dozen of them. Fluvoxamine was by far the best of all of them. It's sedating, which is good for sleep, and more importantly, it has one of the strongest antiinflammatory effects of all antidepressants. It fixed my sleep and gave me more energy. I've been on it for nine years, and the effect has stayed the same for all these years. It's not a cure, I still have plenty of nasty symptoms, but fluvoxamine makes my life much more tolerable. I take 100 mg a day.

If I remember correctly, I started with 25 mg and added 25 mg every 5 days or so, untill I reached the dosage of 100 mg. I had side effects in the first 2-3 weeks (I felt very sleepy at day time), and then then they went away. Right now I don't have any side effects. I've been taking 100 mg at dinner for 9 years.

It's my 2nd day and I feel my mood has been lifted, brain fog is still there, but "lesser" and not so invasive. But I wake up very early on fluvoxamine, not sure why, which makes me quite tired physically.

It usually takes about 2 weeks for SSRIs to work. Hope you'll get better.
I'm not sure why you get up early on fluvoxamine. For me it was the other way around. I used to wake up in the middle of the night and fluvoxamine fixed it.
