It does feel a little weird for the first week or two, but after about a month, I was pretty used to it, and sodas taste kinda over-sugared now.
My diet advice, for what it's worth - if you do nothing else, dump sugary drinks, including soda, fruit juices, energy drinks, etc in favor of water. It's pretty easy as long as you don't try to change everything else at the same time, and every school of thought on nutrition I'm aware of agrees that they're awful. It's also kinda nice to not have to carry everything you drink home from the store.
I didn't really realise lactose intolerance was a thing until I was in mid 20's and moved to the UK.
Many probably don't realize it until they "acquire" it themselves. Or maybe they just start feeling bloated after drinking a lot of milk or eating ice cream, and don't really consider that it might be a mild intolerance.
As far as I know, about 4% or so of the population in Scandinavia is lactose intolerant now, after increased immigration from parts of the world with more widespread lactose intolerance have increased the percentage substantially.
It was simply not on our radar until perhaps the mid 90's.
As for milk... could always tolerate it cold, but not heated (mom microwaves it). Looks like more than half the human population is lactose intolerant:

Milk commercials are so over the top, in bay area radio commercials depict it for people growing up into super heroes (I kid you not).
You should switch from sugary drinks to water and fruit. It takes about 3 weeks to adjust. ( and avoid chocolate milk )
Until I realised what was going on, when I was taking breaks from using 360mg very other day - so equivalent to 5-6 cups of coffee - to boost my weight lifting in periods, I had week long bouts of diarrhoea, intense headaches, shakes setting in in the evening (so severe I had to time my painkillers, or I'd have problems swallowing them because I had difficulty holding my hands steady enough to drink a glass of water), fever, and night sweats.
Caffeine can be a nasty drug to go cold turkey from if your intake has been high. Best bet is to step down gradually (not a long period - over a week or two), coupled with pre-emptively taking paracetamol/acetaminophen in the early evening.
Often, someone who gets a lot of caffeine and starts experiencing symptoms like above may be experiencing withdrawal without being aware.
A lack of that feeling will make you feel less good. Experts say it takes up to a month for that imbalance to normalize.
Great talk about it: https://www.youtube.com/watch?v=aWLnlhLNa28&feature=youtu.be...
The calorie contents of Pepsi is not that far removed from many fruit juice products. Some, like lemonades, can often be higher in sugars than Pepsi.
I need to do find some similar method to stop eating bread now :)
