No regrets here. I am almost 7 years out, and within 20 lbs of goal. I didn't want the lap band because I thought it would cause problems when I ride horses, and I didn't want the malabsorption/maldigestion of bypass (and the idea of loose parts hanging around in there creeped me out!) so I figured the sleeve was best for me.
I did have problems with reflux, especially at first, so I tend to stay away from spicy food, acidic food, or tomato-based food. Even then, still would get reflux at night when in bed. UNTIL I discovered the wedge! Started out on a wedge pillow, then because I roll around a lot, I put my whole mattress on a wedge. Then when my mattress needed replacing, I got a mattress with an adjustable base, so I can elevate my upper body as much as I want.
From the FIRST NIGHT with the wedge pillow, I have not had any reflux at night! It seems to have even helped with daytime reflux, although I'm not sure why. Just glad it's gone!
If you don't want to deal with wedges, try putting the legs at the head of your bed up on blocks.
