Photoshop :: Printer Profiles

I have recently started using a printer profile (Epson photo 1270). My query is this. I take a picture with my camera (Canon 10D), which when viewed on my monitor in ACDsee looks about right, colors ok, just needs a few touches here and there maybe. I then open it in Photoshop using the printer profile and the pictures looks very different. Now I realise what is happening but I am having great trouble adjusting the picture back to how it looked originally(which I was fairly happy with). I also know that if I can adjust the picture to how it looked it will print out almost identical to how it looks on the screen, so that is ok. It just takes a lot of time to do this using the Photoshop tools, and it is so hit and miss to try and put it right and get back to the original colors etc. Is there a shortcut that can be used, using the color values from the original view before it was opened in Photoshop or something like that? It just seems a lot of work for every individual photograph I may want to print out. I can compare the two views of the same photograph by having Photoshop and ACDsee open together.
