Doesn't everyone ever feel unusually heavy after a meal? How about Cutslin Anti-Spike?

My lifestyle has changed a lot lately as working from home has become more common. I used to be quite active because I commuted to work, but now that I sit all day, I find myself feeling unusually heavy and drowsy after meals. I was particularly concerned because my concentration would drop all afternoon on days when I ate a hearty lunch. Then, a close colleague recommended Cutslin Anti-Spike. I became interested because they said blood sugar management is important not only for dieting but also for maintaining my daily condition. Honestly, I used to be indifferent to this kind of thing, but now I'm wondering if it's time to start taking care of my health. I happened to look up Cutslin Anti-Spike and found quite a few reviews, and everyone seems satisfied, so I'm curious to try it. It's too difficult to change my eating habits suddenly, so I'm considering getting some help like this. Are there any of you who take Cutslin Anti-Spike consistently? If anyone has tried it and experienced post-meal lethargy or other physical changes, I would appreciate your advice. Could you share some tips on how you all manage this?
