I started using a spray b12 (under the tongue) about 4 weeks ago and have definitely noticed an upturn in energy, but a down turn in mood.
I don't know what's done it or whether it will be permanent, as I also have had 5 weeks of vit d (20,000units) for hyperparathyroidism as well... Though last time I took these they had zilch effect at all.
Anyone know what could be happening?
