So far with the rny there are no seriously swallowing issues. I know if I drink too fast it's uncomfortable. Or if I eat too fast I burp A LOT. I'm not even a full month out yet but I noticed I am a slow loser. And I hit my first stall at about 2 weeks that lasted about 8 days. After that I started losing again slow but steady. Since my highest weight I've lost about 20lbs. Sent from my SM-G935T using BariatricPal mobile app
