Reta questions/reta dosing

Curious people's thoughts/experiences on three things:

1 Splitting their dosing in half and doing it twice a week vs. taking their full amount once a week.
2. Overall dosing. Where your sweet spot is and what you may have found to be too high.
3. How long to use Reta before stopping or taking a break ot sorts?

Bonus: what helps the acid reflux? Only side effect that bugs me. Considering nexium. Tums not working.

My background. Started Reta ~ 3 weeks ago. Did 1mg (0.5mg twice/week) for weeks 1-3. Just bumped up to 2mg (1mg twice/week). No real difference on the scale, although I can see a physical difference. Have been sticking to protein goals and lifting 3-4x a week, so l assume I'm undergoing an overall body comp, which I'm totally cool with. Not overthinking the scale.
