I agree with unbreakable. Unfortunately cost is going to be a big issue, but it beats becoming homeless because you did not take preventive measures. Install 20A half breakers, if room is an issue. Or, at best, you might be able to install a 100A sub-panel, clean things up at the main. Then make your dedicated circuits for lights, receptcals, dishwasher, dryer, kitchen/bath, spare room, etc... Dedicated2- 20A breakers (12/2 romex) is a min. /NEC. Consult with a qualified electrician. Also, check out Tauton press fine homebuilding electrical great resource.
