Nitro
Hope your ok soon Gareth.
Do you know one of the treatments for this condition is Glyserol Trinitrate ( aka Nitro Glyserine )
Organic compound, powerful explosive and ingredient of most forms of dynamite. It is a colourless, oily, somewhat toxic liquid with a sweet, burning taste. Its safe use as a blasting explosive became possible after Alfred P. Nobel developed dynamite in the 1860s with an inert porous material (moderator) such as charcoal or diatomaceous earth. Nitroglycerin is also used in a mixture in rocket propellants. In medicine, it is used to dilate blood vessels, especially to ease angina pectoris.
