Everyone responds differently, could go completely smooth for you, or you might just deal with mild digestive slowdown since it delays gastric emptying. Millions are on this medication (a sizable chunk of both the US and Canadian population), yet only a small fraction show up in communities like this. Places like this tend to attract people currently struggling or who've struggled before and want to help others through it.
This class of drug also gets prescribed for diabetes, plus certain heart conditions since it offers cardiac protection, and kidney disease too, since it protects kidney function, though patients still need to stay hydrated enough for the kidneys to function properly.
Mindset matters a lot here. Look online for the positive experiences too, or check actual data. Roughly half of everyone taking this medication reports zero side effects whatsoever. Among those who do experience something, most cases are mild and clear up within a few weeks. There's solid data tracking different reactions and how common each one actually is. Staying well hydrated is honestly the missing piece for so many folks, water's essential for flushing out toxins and waste.
