The deed is finally done!
to stay ahead of the nausea by taking Maxolon and Phenergan before it was necessary;
to stay ahead of the gas by taking charcoal in between (separated from other meds by at least 2 hours) [so much better than simethicone, which we both found practially useless]
keeping hydrated with frequent sips of water
moving and walking to help move gas as often as you can bear.
Of course, Lisa is a real nurse and was much better equipped to help me than I was her (I feel sorry for her that she had to have an inept ex-pharmacist look after her) and I'm sure I wouldn't be feeling so cheery if it wasn't for her wonderful care (Thanks babe).
