mineral or vitamin deficiency

A deficiency in vitamin B12 (pyridoxine) and or B6 (pyridoxine) will produce excessive sweating, excessive urination, dizzy spells, ataxia (tripping over), chest pains and heart palpitations, numbness and tingling and prickling sensations in the outer extremities, depression, headaches and migraines, muscle cramping and night sweats.

B12 and B6 NEED sufficient calcium to be effectively assimilated.

Some symptoms of calcium deficiency are headaches and migraines, insomnia, achy bones, moodiness and irritability, digestive issues such as bloating cramping and constipation.

Most over the counter (otc) and prescription meds, such as antidepressants, will trash calcium and magnesium as will a diet high in processed sugar, processed salt, animal protein, saturated fat, caffeine, alcohol, sodas / pop. Other things that will trash your calcium supplies are laxatives, diuretics, and estrogen supplementation.

So... eat more green leafy vegies and green salads, fresh salmon and fresh sardines, which are all rich in both calcium and magnesium.
Try juicing celery and limes and drinking that each morning... rich in calcium and magnesium and an easy way to ingest lots of greens if you don't like eating salads.

Eat more foods rich in B12 and B6:
B12 - lean meats and fishes, eggs, cheese
B6 - lean meats and fishes, raw nuts and seeds (only a handfull daily ground up for easier digestion), brown rice, rolled oats.
