If you are unable to bear EC, you can manually peel off your lips and live. For this, before going to bed (after brushing) apply a layer of vaseline over your lips. In the morning after brushing your teeth, take a ear cotton bud and peel off the extra skin. It is negligibly painful and my lips look normal throughout the day.
But i do not know about the long term effects of it. But many people with EC have been doing it and hopefully they are doing well.
