Does anyone know how long does it take to cure hypoglycemia?

I'm been having this for over a month now. Everytime I get dizzy I would drink orange juice, then it becomes better. I wonder is there a way to cure it? Because sometimes when I'm driving, I'm afraid the symptoms strike and I don't know what to do. I might collape and no one is there. Please help me.
Hey thanks for the advice healthy girl. I was wondering it's to lose weight because most of the time I get hunger every 3 hours. Can I have your email so that i need to ask some questions. If ur not okay with it. Still thanks though.
Thank you everyone for the wonderfull advice. That is what i wanted to know.
Thank you everyone for the advice. I really appreciated.
By the way the doctors told me that I have reactive hypoglycemic.
Do you think ensure would able to help with symptoms if i were to drink it everyday.
