Quick question is it possible to length the time NovoRapid lasts in the system? I know the average shot is supposed to peak between hours 1-2 and typically the shot is out of steam by about 4-5 hours. Question I'm asking is can I make that last for an extra hour or 2 by taking an additional 2-3 units and then having a small snack in-between hours to stop a low? Used to be able to do this on the 30/70 regime.
Novorapid peak time is roughly 75 mins, as you note, and typically it takes between 5 and 7 hours to get fully out of your system. Taking more doesn't really lengthen the duration of the action, so that approach wouldn't work.
I guess the question is "Why are you looking to do that?"...
Because around the 5-8pm my sugars start to raise, I can only assume that this is the Lantus running out as I usually take the Lantus around 8pm with my evening meal NR shot, taking any more Lantus would cause lows around the 4-6am mark. So was wondering if I could add a couple more units in afternoon NR shot.

Not really, no. The alternative is to either split you lantus does to make it twice daily and try to achieve a flatter profile, or to ask for Levemir, which generally manages split doses much more effectively.
There are people that do do a small shot of rapid acting insulin to counteract the effect of basal running out - not ideal but if it works then fine, but most don't pre-inject before the rise like you were suggesting (just in case the rise doesn't happen!).
The optimum solution is to get a basal regime that works though. You may want to do a basal test to provide evidence to your HCPs and together you can change things.
