Wow thanks for all the replys everyone. I definitely need vit. D3 as do most people living in Ireland what with the lack of sunlight especially in the winter months as this is when I become most depressed. I love the cold weather I just hate the short days.

I went and got a few bits and this is what I'm taking 2x per day. It may seem exessive but I always take a bit more than the stated dose(of supplements)and alcohol and cocaine for a period.

Magnesium 500mg
Omega 369 2000mg
Vit.c 2000mg
B-complex 1 tab
Multivitamin 1 tab
Vit.d3 4400iu

Again it might seem excessive but it hardly gonna kill me.
