As I posted a minute ago on another thread, no or minor problems is by far the norm for WLS surgeries.
People tend to post about problems, looking for help, support, just to rant, or in some cases to get pity. It's human nature. Folks having troubles early post op are working to get to were most people are: On plan.
People with little to no problem generally just keep doing it quietly. And yet, unusually, we have 2 threads today about contrary to apparently most others, things are going well.
If things are going rough, keep working and you will get (up) to plan. You will get there with focus, effort, persistence, time and in some cases medical and/or moral support.
Once you get to plan, whether it was easy or hard, stay laser focused on staying on plan. For some it's hard to get up to plan for others it's hard to stay down to plan.
It is easiest to stay on plan in the first few months. Use these months to make your plan normal. It will serve you later.
Continued good luck,
