Exactly this. When people used to have smoking patches on their arm to wean them off smoking, once the cravings had died down, and they smoked no more, they didn't carry on using the patches - or smoke again. (Most didn't resume smoking anyway.) The idea was to use a particular aid to stop a habit, and then ditching it when it has stopped.
WLI surely is the same in principle. I find it unfathomable that anyone would plan to use these injections for life, even when they are down to their 'target weight.' Just so they don't put the weight back on. How about using some good old fashioned willpower? These jabs are meant to retrain your mind, and I don't understand why people keep taking them, long term.
It's an aid to weight loss. Why would you want to be dependent on these for life? This is a ticking time bomb for many, and a lot of people are terrified of losing them, or them going to such a high price that they can't afford them. Several posters have already got into debt to buy them privately. This is going to be a financial disaster for millions. They will stop paying for certain things/bills so they can get the WLI. Time for people to start weaning themselves off them.
Surely no-one would want to take these for life anyway, even if they weren't expensive? I know SOME meds are taken for life, for certain illnesses, but this is not a normal med. It's an aid to weight loss. (And being overweight is not an 'illness.') Once you have lost the weight, and trained your eating habits to be better, there should be no need to carry on using WLI.
And never mind 'tell me you know nothing about WLI without telling me you know nothing about WLI.' there should not be any need for someone to keep taking WLI once they get the desired result. The WLI retrains your mind and feelings about food, as well as helping you get to your target weight, so once you're at target, you don't need to keep taking them for life...
The 'alcoholics 3 weeks off booze thing' is a poor example OP. You have been taking the WLI for a YEAR and lost 5 stone. Taking WLI for life is untenable for many reasons, especially financial. No-one is going to be able to do it. Time to start weaning yourself off them now, and working on that willpower.
