Lantus is not fast acting.  It typically lasts for 24 hrs but some people I know have to take it more than once a day.  I am lucky in that when my blood sugars are low, I feel it.  My heart races, I feel shaky and it actually wakes me up.  The problem is by the time I get to that point, it's VERY low.  It's better to catch it before it gets that bad.  I've also heard about the bad dream thing.  I think people get stressed out during nightmares and blood sugars can dip. 

"Very high" to me is subjective.  I hit the 200's atleast a couple of times a week just due to struggles of my own.  300's would be a HUGE concern to me. I feel best when I'm below 130 but above 80.  There are people who keep in the 70's or lower and feel fine, but not me.  I know that it's easier to maintain tighter control on a pump but I just haven't made that choice yet. I take 15 units of Lantus in the morning and take Humalog with meals (sliding scale depending on carbs).

You just found out about the Diabetes and I applaud you for asking questions and taking an active role in your treatment.  You're going to figure all of this out.  Your taking very low dosages right now and I suspect that in time you'll need more.  You're in a "honeymoon period" right now I would imagine.  Just keep good track of what you eat and what dosages you take.  I'm sure your doctor and you will get all of this figured out.  :)  You can PM me anytime!

i am 2 years out and just started running into hypoglycemia, i think reactive but not sure.  Im actually pretty mad about it, nobody ever said i would have any problems like this, and i actually found out i may have this because i had a seizure on sat. from it.  Sooooo mad.....  now i am so parinoid and i check it all the time and all i eat is protien and veggies because im so scared.  I though surgery was supposed to help get rid of these things not create them, so ur telling me i was healthier before i had surgery?  Im just angry and not quite sure of this anymore.

 Yes, being over 100 after an overnight fasting is too high IMO.  Perhaps you should be tested for PCOS.  There are certain subgroups of type 2 diabetics that have more trouble with fasting glucose than they do with post-prandial, but they're not the most common.  I doubt those sugars though are related to dizziness or blurred vision.

Hey there.  I've been a Type 1 for 17 years.  I wonder why your doc didn't cut you back a little.  My doc would rather me run high than low (although neither is preferable).  Even now depending on the time of the month, how much I'm exercising, etc. can affect how much meal time insulin I take.  I hope that you get better control.  I know how bad low blood sugars feel.  I recently had to switch from taking Lantus at bedtime to morning.  Occasionally I would wake up in the middle of the night EXTREMELY low...like 30's.  I was always scared that eventually I wouldn't wake up.  No problems since switching it to the morning and didn't even change the dosage.  Good luck!

 Thanks for the reply.  I am probably worrying about the small stuff
