Please help me, as I'm drinking too much because of lack of inspiration. 
I have virtually no sweet tooth for drinks. I can cope with bitter lemon but find the taste of sweetener a bit grim. I like lime and soda. I drink almost entirely fizzy water as there's so little else out there, and now I'm drinking cold white wine out of boredom.
I love, love citron presse in France, when I can add tiny amounts of sugar. I've occasionally found lovely non-sweet lemon cordials (for £££s) which then get discontinued.
Any suggestions for cordials/soft drinks I've missed that aren't sweet? I don't like non-alcoholic wine but occasionally have the beers. Not really my go-to though.
