Hi type1bri
It did help dropping the lantus to 7. My experience so far is if your dropping and having hypos you need to check your background insulin. I got this advice from a member... I've cut and paste it but the link is at the bottom it this thread.
Daytime
Get up, test your BS, take any medications you require including basal insulin if that’s when you normally take it. Do not take any fast-acting insulin. Do not eat breakfast. Test mid-morning and prior to lunch.
If your basal dose is correct, your BS by lunchtime should be within approx.10% of what it was when you got up.
If not take more or less basal insulin – never adjust by more than 2 units up or down.
Repeat the ‘miss breakfast’ test at least 3 days hence, to see if it’s right. Keep repeating this until it is more or less right!
Make sure you are happy that that bit is right, then next do the same again but miss lunch. Your pre-lunch and pre-dinner readings should be similar now.
Then do exactly the same pre-dinner, missing dinner – and pre-bed.
Then move on to overnight.
