3 weeks 8lb lost and some questions

Hey folks, I've been lurking here for a bit and finally decided to post about my own start with semaglutide. I'm 32 and was hovering around 220 lbs for way too long, mostly from desk job stress and bad eating habits, so I bit the bullet and got a compounded version through TrimRx.com after reading some good things about their process. It's only been about three weeks, but ngl the nausea hits hard some mornings, though I've already dropped like 8 lbs which feels amazing. Anyone else dealing with that weird foggy brain feeling in the afternoons, or is it just me adjusting? Would love to hear how you all powered through the early days.
