Absolutely no regret. I lost 28kg, another 12kg to go. I lost weight (less) with WeightWatchers 20 years ago and that was still a constant battle.
Now my head is clear of food noise, I concentrate on re-learning how and what to eat and can also enjoy life again.
I still eat 3x a day, the odd snack but that's not 1-2x a week, not a daily one. My alcohol consume is down, I feel a lot better, not just because the weight is down.
For me it started fairly quickly that I didn't have any hunger. I am still on 5mg and that does not suppress it fully but enough and it enables me to learn making good choices.
I have constipation but then I am always prone to it. I may have the odd time with an upset stomach or feeling a bit off but nothing like the fairly long list of side effects. It's important to check them, yes but it's also important to realise that some are 1 in 10,000 people.
A healthy loss is between 1-2lb a week, it's not designed to shed the pounds in a matter of weeks, you need to see it long term.
