Brilliant, thank you for your comments, I'm lucky in that my husband doesn't mind the possibility of me staying over during the week, I think he's actually looking forward to the peace and quiet..
It's nice to hear that it is possible to do it, and I like the idea of doing work on the journey. I'll have to just keep an open mind and take it as it comes.
Thanks again!

Hey, thanks for the replies. The PhD in psychology.. a direct train takes just over two hours, the hours are regular office hours so I will intend on staying over a few days during the week as I have friends with who I can stay with. I am married and live on a farm which is why I am unable to commit to a complete move, but think I may give it ago.

Thanks again for your advice guys :)

I am currently living in North Wales but wish to do my PhD in London.. is it an absurd idea to commute daily? I travel to London regularly at the moment but was wondering if it's feasible to do it on a daily basis???
