So many people have the luxury of deciding if they will see the doctor or not. As diabetics we do not have that luxury. No matter how good you are, or how aware you are, nothing can substitute for seeing the doctor.
I speak from experience, I went over 20 years without seeing a doctor, and during those years of self medication I was afraid, ashamed, disgusted and angry with myself.
Today I see more than 15 doctors because of the damage done. As one wise doctor told me, it is a pay me now or pay me later proposition.
Of course we do not have time, our Alc is nto perfect, we have gained weight, or whatever the excuse. I ended up dodging the doctor for 20 years, and now see them constantly.
It is an uneven bargain. Save the hassle when your fifty, see the doc when your iffy.
