Hi. As previously mentioned, I've been SI 1000mcg Hydroxycobalamin every other day for just under 2 weeks. At the moment my neuropsychiatric symptoms are very bad, and (unfortunately) seem to be getting worse daily at the moment. Am taking co-factors, but am being tentative with the potassium addition as I'm taking a medication which maintains the body's potassium.
Am contacting GP as seem to be spiralling into full-blown depression, which borders on suicidal at times.
My other symptoms (as before I started this journey) are rapid weight loss, loss of appetite, breathlessness, brain fog, loss of balance, inability to find words. This came on rapidly a couple of months ago, although had had other symptoms for a while as well. My folate was very low (2.6) and active B12 low (33) but my iron was actually pretty good. I did take 5mg of folic acid for 6 days before I started the injections, hoping it would stop the B12 from depleting my meagre folate, and vice versa. I'm still taking the folic acid and gentle iron EOD.
However, when I've self-injected recently, the symptoms almost completely disappear for 4-6 hours. My appetite returns, I don't feel depressed, my cognitive functions improve dramatically, and my wife even says I look a different colour! After 4-6 hourse I feel things tailing off and by the evening I'm back as I was, with sleep the only relief. The next day I'm back to feeling terrible until the following day's injection.
The other thing that has happened the last time is feeling incredibly cold after the injection, to the point I'm shivering in warm sunshine.
Do either of these reactions sound normal? How can the B12 injection have such a marked (if temporary) effect? Do others experience this?
