Hi, I don't think my original post was very clear but I'm only doing the journey twice a week: from Sheffield (S10 area) to Manchester (m23 area) on a friday night and back again on a Sunday night.
For the person who put that I shouldn't be driving if I don't like driving at night: learn to read. I put that I don't want to drive on snake pass at night, not avoid driving at night all together.
But thanks everyone for all the responses, it's given me loads to go on! Don't feel half as nervous any more. :)
