brown urine

Is brown urine a known effect of using MMS?

I did the starting procedure then went to 1 drop doses every hour and then noticed this. I found this study which mentions sodium chlorite and brown urine:

I am in normal physical health except for fatigue.

Ingested MMS1 does contain a lot of residual MMS. You might want to try CDS, which is only CLO2 gas in water. 

It turns out it's actually pink-orange.

If there is residual MMS then would it make sense to add more acid to make sure it all gets activated?

Stomach acid should activate some of the residual MMS. But, Jim wants MMS to travel further into the body to activate elsewhere. That is one reason he only wants to activate MMS for 30 seconds.
