I am trying to check my glucose to see if I may have diabetes because I can not afford to go to the doctor at the moment. I want to start charting how I feel and what my glucose level means. I can not find any charts for what my numbers mean after or before I eat. Can anyone give me any info. on what range is bad and good after or before you eat. Thank you so much. I have a feeling Im diabetic and its probley good for me to get a head start on understanding this. Please dont tell me to go to the doctor because I am going I just want to have a journal of how I feel before I go, so if Im not diabetic they can find out what it is. Thank you so much.
