how long do you guys wait until after youve injected to eat?

I wait about 15 to 20 minutes to avoid a spike, it depends on what I'm eating, slow acting carbs I may wait until after eating.

Depends what is convenient.
Ideally 30 to 40 minutes.
If eating out, I inject once I have seen my food and then start eating unless I don't know how much I will eat (e.g. if I don't know if I will like it) I inject after eating.
In short, I inject once I am able to calculate how many carbs I will/have eaten.

I wait about that too but other diabetics I have spoken to all have different times they wait

do you ever find that you drop if time gets the better of you?
Im always anxious of that

I assume you are referring to the ideal time.
I am an occasional Libre user in order to spot trends.
One trend I spotted was a spike about 30 minutes after eating when I injected just before. It was this trend that I used to calculate when I would ideally inject. It was not a random decision or guess.
Without such facts, I would have injected only 15 minutes before eating.

I should add that I use NovoRapid.
I am soon changing to Fiasp (when I have used my NovoRapid supplies) and hope to see the pre-eating injection time reduce.
I know different fast acting insulins react at different rates and different people see different reaction rates for the same insulin types.

And if I am eating slow release carbs (e.g. pizza) I will double inject - once before eating and a couple of hours later.

I need advice on what are slow release carbs and fast ones as I have no idea

There are some guides like fatty foods (e.g. chocolate and pizza) tend to be slower release but others may be a bit of a surprise.
Have a read about "Glycaemic Index" - this is the measure of how fast carbs are absorbed.
We all react slightly different so, if you want to find out what is slow for you (rather than "in general"), trialling a Libre is very useful. Unfortunately, it is difficult to get this on the NHS but even one Libre, which lasts for 2 weeks, can provide excellent data if you use it as more than a finger prick replacement.
The cheapest option for purchasing the Libre in the UK, at the moment, seems to be Asda where they sell them for £44 each.

Yes we are all different

okay so it might be trickier to get on via my doctor or specialist nurse and I can get one over the counter at the chemist? I have heard alot about libres and people getting them from asda

Exactly.
It is worthwhile asking your doctor/diabetes team but don't hold your breath.
In some parts of the country, they are treating the criteria for getting them incredibly strictly (e.g. in my area I have to have had 2 hospitalisations due to DKA or 2 severe hypos needing assistance from someone else); other parts of the country understand the value much more and have more relaxed criteria.
If you go down the Asda route, I think you need to call in advance to order the Libre as they do not have them lying around on their shelves. For me, I called the local Asda pharmacy one day and they called me back two days later to say they had them for me.
