All I can say is listen or know your body, if you're in pain/vomit/faint during or after excerising just stop the excerise for the day or two for your body to rebuild itself and when you do some weight lifting the next day take a break from the weights for a day cause of sore muscles and you create muscles when your relaxing anyway. Then the next day, if you feel any better do some excerises.

Oh and don't go for a routine, keep the body guessing; that's usually gives you better results.
