Can't Decide Between 4mm and 5mm Permalip

I am scheduled for January 3rd, however, still battling the decision of what size to get. I would like to go with the 5mm to make the procedure worth it, since my fear is that the 4 mm is playing it too safe and may be too subtle. Although I want to make my mouth bigger, I don't want them to look unnatural or like sausages. I don't have super thin lips, however I have a very narrow mouth that isn't wide, so I'm wondering how the implants would look with the shape of my lips. any feedback is greatly appreciated! Will update!

I am about 3-4 hours post-op and starting to finally feel as though the pin is manageable. When I first got into my car I was still numbed up but the pain was already kicking in and they swelled up right away. I had to say the pain was excruciating for a bit and did not settle until I took some pain meds, that really helped. It's hard to close my mouth all the way and have to force it shut therefore it's hard to swallow. However, definitely easier to close my mouth at the moment and I'm feeling a lot better about things.

As far as the procedure, it went better than I expected. It was a little uncomfortable at first until I told him to numb me more. Then I was amazed at how little I could feel. Couldn't even really feel the tugging. My dr. Recommend going with 4mm since it would create a pocket so that I could then go with the 5mm later on if I still wanted them bigger. Despite this I still decided to go with the 5mm becuase I wanted to see a difference. I may regret this in a week when I need to go back into work and look like sausage lips, but, who knows, maybe, they will turn out better than I expected!

I feel as though the swelling and pain after the procedure was awful I could barely function. So I hope I am past the worst.

I woke up with my lips being more swollen then they where the first day, though they are no longer uncomfortable. They are also bruised on the inside of my lips. Eating isn't too difficult as long as I eat soft foods and need to drink carefully with liquids. I am worried about food getting caught in the stitches therefore I try to rinse my mouth under the facet after I eat.
Talking is still very difficult as I can't open my mouth very wide due to the stitches, therefore I have been only mumbling when I need to talk.
The images from today look a bit unsightly. I smeared my lips in tons of aquaphor and also did an at home chemical peel since I am out for a week anyways. Therefore my skin also looks a little rough around the edges.
