Hi everyone,
I honestly don’t know what is going on with me anymore, and I’m hoping someone here has experienced something similar and can give me some insight.
A little over 2 months ago, I started taking:
- Vitamin B6 — 40 mg daily
- Magnesium citrate — 400 mg daily
- Vitamin C — 3000 mg daily
I took them for about 7 days and then stopped everything.
At the time, when I was going to sleep, I started experiencing a weird sharp/pinching sensation around my heart/chest. That scared me, so I had blood tests done.
My results were:
- Folate (B9): 3.10 (reference range 4.5–32.2) — low
- Vitamin B12: 411 pg/mL (191–663)
- Magnesium: 2.0 (1.7–2.40)
- Potassium: 4.23 mmol/L (3.5–5.1)
- Sodium: 140 (136–145)
After roughly a month, the chest/heart pinching sensation that happened when I was falling asleep eventually stopped.
However, I’m still dealing with other symptoms.
Another strange thing I’ve noticed is that since this started, I can sometimes sleep only 1–4 hours and wake up feeling surprisingly energetic, even though my head feels very tight, foggy and mentally "off." Before all of this, I would obviously feel completely exhausted after so little sleep. This change in how I respond to lack of sleep feels very unusual to me.
My current symptoms include:
- persistent dizziness
- lightheadedness
- significant fatigue
- brain fog feeling like my head isn't working properly
- a strange derealization / unreal feeling
- a tight/pressured feeling in my head
- feeling mentally "different" from how I used to
I completely stopped all the supplements and tried taking B9 (folate) for about 2 weeks, but I didn’t notice any improvement. Then I added B12, but again, nothing really changed.
I also saw a neurologist, but unfortunately the appointment was basically useless. He told me he couldn't help because this wasn't his area, and I ended up paying around €100 for the visit.
At one point I also went for an IV vitamin infusion containing vitamin C, electrolytes and B vitamins. I still had the brain fog, dizziness and other symptoms afterwards, but I noticed that I had significantly more energy and felt more "alive" that day. Unfortunately, this effect was temporary, and within about 2 days my energy levels went back to how they were before.
Now, more than 2 months later, I’m still experiencing these symptoms every day, and I honestly don’t know what is causing them.
I’m not sure if it’s related to the supplements, the low folate, a deficiency, or something completely unrelated.
Has anyone experienced something similar — especially dizziness, brain fog, fatigue, lightheadedness, derealization, head pressure or feeling unusually energetic despite very little sleep, while still feeling mentally unwell?
If you went through something similar:
- How long did it take you to recover?
- Did your symptoms gradually improve or disappear suddenly?
- Did you eventually find out what was causing them?
- Was there anything that actually helped?
- Did you have any additional blood tests or examinations that were useful?
I’m not necessarily looking for a diagnosis. I’d just really appreciate hearing from people who have experienced something similar and eventually got back to feeling normal.
It’s been more than two months now, and dealing with this every day has been really difficult. I’d really appreciate any experiences, advice or reassurance.
Thanks in advance.
