Switching insulin

That's strange advice. With modern insulins you should be able to adjust your insulin to your food, not the other way around.
Have you done a DAFNE course or such? That could be very helpful.

Can it be he meant you don't need to eat 5 meals a day anymore if you don't want to, not that you cannot eat them if it suits you?

I think Apidra works slightly differently to some insulins. Have you looked at the manufacturers website @Steve14 ?

https://www.apidra.com/about/dosing

From googling Isuman Rapid, (e.g. Isuman Rapid insulin profile) it appears to have an action similar to Regular insulin.
If you google 'Apidra insulin profile' the graph shows a more rapid action profile and is often quoted as similar to other faster acting insulins like Novorapid and Humalog.
One use of Isuman Rapid insulin is in a regime promoted by Dr Bernstein in his book 'Diabetes Solution' (and exemplified on sites like True Grit Type One - which also reports the advantages of lower HBAiC and loew BSL variability and very low rate of hypos) where he shows that it is possible to achieve normal or near normal BSLs and HBA!C. Part of this regime, as he writes, involves a very low carb diet.
In contrast to what @Antje77 says about Apidra and DAFNE (Dose Adjustment For Normal Eating), the Bernstein approach, which I use, adapts the diet to the action of the insulin.
The question is, can you eat want what you like and dose for it (DAFNE) with Apidra and maintain HBA!C of less than 6% and BSL variability of 4 to 6.4 mmol/l and minimal hypos?
I wish you luck with Apidra and sorry if you were not given the opportunity to use Isuman Rapid to its full potential but felt that in switching insulins it might be helpful to contrast the effect and potential of each insulin.
The above is not medical advice or opinion, just based on my own experience of 53 years on insulin and my diabetes education.

when i was first diagnosed i was put on apidra and you dont have to stick to 3 meals a day if you snack inbetween just be aware of i.o.b its all trial and error your eating habits should not have to change

No contrast here, @kitedoc . If you're comfortable dosing for different foods, like they teach you at DAFNE, you can choose low carb foods as well if that suits you. If you don't know how to adjust your dosing, you can't use Bernsteins approach either.

Right now it seems you're struggling to eat 2 sandwiches and a banana for breakfast because your doctor has told you you must eat that much, @Steve14 . If a course can give you a better understanding of how to use your insulin it will give you much more freedom with food, be it a Bernstein like approach or the food you're used to eating.

So do I have to inject myself more than 4x times a day from now on? I wouldn't be a fan of that.

You might have to take more injections than that honestly if you want good results. The idea is to take insulin whenever you need it, so yes, everytime you eat basically anything you have to inject, as well as when you need to correct highs. There are days when I might inject 10 times, but it's really not a big deal. It's better than having to stick to a strict schedule, and it's better than the days before pens and the crazy small pen needles that you can get now. You just get used to it after a while and it shouldn't hurt unless you hit a bad spot or re-use a needle too many times.

As far as I am aware DAFNE is not about dosing for protein and thus there is a distinct contrast.

I've been on Apidra for a while, although using a pump rather than injections. I would agree with the statement about taking it after meals, and I try to take it 15 minutes before eating.

I don't take insulin because I hate needles. My doctor is trying to put me on inhaled insulin instead.

How long have you been type 1 AND how are you keeping your bloods in check with no insulin??

About four or five years now. I've been avoiding foods that are sugary and trying to switch to other foods that will help lower blood sugars. SO far in four months I dropped two points on my AIC.
