I've had a Vitamin D deficiency for almost 2 years and it first reared its unattractive head with deep yawns, nausea, heart palpitations and arrythmia, dizziness (oh darn, etc., etc.). Soon I also experienced heart pain for over a year (which has since almost completely disappeared). Thank you for mentioning your deep yawns and shortness of breath. A year after vitamin D supplementation I still get those, but only for a few minutes every few days - and I'm perhaps a few months away from full recovery. I hope you stuck with your Vitamin D supplementation and are now free.
Hi there... Hope you're doing well and had a nice Christmas.
