At the moment- probably yeah 🙂 Acutally its probably better to say caffeine as I also smash down teas and energy drinks. I got addicted to caffeine in uni. I went on a mission back them to get rid of it and managed to replace my addiciton with water (alot more healthier but man, you go to the toilet a lot). Its just been the last 6 months or so, since nearing the end of the PhD, that it has creeped up again. Will begin to try and get rid of the habit again in a couple of weeks I think.
