Hi Trevann, welcome to the forum.
I have been on Lantus since last October and inject once a day in the morning at around 7am and am currently on 34 units.
Once you decide what time you will inject, it is important to inject at that time or as near to it as possible (usually within 1 hour). This is because if you alter the time you inject too much it can effect the absorption rate of the insulin and will cause you to get erratic BS readings thus making it harder for your Doctor or Nurse to make adjustments to your dosage.
When do you take your insulin?
