| When you say you worry about your #s dropping to fast in the "100s" I hope you meant that as in between 100 & 110...not between 100 & 200! Because if you're keeping your numbers above 200 to avoid going low you may be doing serious damage to your body - that could cause serious issues MUCH worse than going low on occasion.
Yes, lows are scary/incovenient/yes even dangerous, but I'd say going blind, or losing a limb is even worse.
I know you said you've talked to your doctor about nausea & I hope he/she is able to help you out with that. You might want to talk to him about your fears of going low. He might be able to help you find a healthy balance. Maybe even the pump will help with that if you learn how to use it to it's fullest ability. |
