AITA for drinking fruit juice when my partner has said he doesn't like it?

Let me give you some background. I (26F) have been drinking diluted summer fruits juice all my life because I hate drinking water. When I do try drinking water I physically wretch due to the anxiety it gives me trying to drink it. So I stay hydrated by drinking diluted cordial.

When I met my current partner (34M, let's call him Jim) I was drinking 30% cordial 70% water, which I admit now was strong. About 6 months into my relationship with Jim, he confessed he didn't like me drinking the juice because it made my breath smell bad (of the juice), it stopped me trying new foods and it stopped us from travelling cheap because we would have to pay for baggage just so I can take the juice on holiday. He even compared it to an addiction and how he was able to quit smoking so I can quit this.

We decided to compromise and 1 year later I had reduced it down to 5% cordial. I was able to take my juice in mini aeroplane bottles and I had to admit I was tasting food better.

However Jim was still not happy and we keep getting into fights about how 'disgusting' it is and it is putting him off wanting to kiss me. I can't even have other fruit flavoured drinks because Jim says it smells and tastes too similar.

So I tried to give it up for him. It has been a month of attempting to drink sugar water. I am getting panic attacks and dehydrated because I'm not drinking enough. I am considering going back to the cordial because of this but I am worried I'd be letting myself and Jim down.

AITA for wanting to drink fruit juice or do I need to keep pushing?
