ok good info. always smart to hit dietary magnesium first. can you tell me more about the magnesium tablets you were using? ie what dose per pill, how much were you taking that caused a problem, and what form were they (eg, were they mag oxide, mag citrate, mag glycinate, or something else?)
also, how much vit D are you taking daily? is it vit d3? when it comes to supplements, it's definitely best to take vit d3 with magnesium.
for dietary - certain whole foods provide naturally occurring vit d3 (eg seafood, liver, kidney, and mushrooms).

as far as symptoms - I definitely have had symptoms directly caused by magnesium deficit. muscle spasms and difficulty swallowing in particular.
hyperreflexia has been found in those with copper and niacin deficiencies, as well as in patients with low magnesium levels.

copper: "We describe three patients suffering from severe spasticity, ataxia and hyperreflexia and had laboratory evidence of copper deficiency." http://www.sciencedirect.com/science/ar ... 0X1000016X
"Diffuse hyperreflexia was found after the seizures. While serum magnesium levels were extremely low"

I can't get the full text of this study to get the context of this quote, but fwiw:
"Marked irritability of the muscles to percussion was noted, as well as generalized hyperreflexia with sustained knee and ankle clonus. ... Imme¬ diately after the seizure, prior to administration of the calcium or magnesium, the serum magnesium was 0.5 mEq/liter, confirming..."

magnesium has successfully been used to treat hyperreflexia:
"We discovered dramatically beneficial effects of magnesium sulfate on autonomic hyperreflexia during labor in a patient with spinal cord injury at a high level." http://www.ncbi.nlm.nih.gov/pubmed/10942492
"We report the successful use of i.v. magnesium sulphate to control life‐threatening autonomic hyper‐reflexia associated with chronic spinal cord injury in the intensive care environment" http://bja.oxfordjournals.org/content/88/3/434.short
"Hyperreflexia was the main indication to start magnesium sulphate treatment (75%)." http://europepmc.org/abstract/MED/15767 ... MYB3u8fj.2
