When detoxing/cleansing is there precautions us gastric bypass patients have to take?

I'd like to detox and cleanse after a few drinks and in hopes I just feel better in general. Also, I've also been experiencing very painful bloating. What can I do to IMMEDIATELY relieve this pain? (Because it's sometimes unbearable) I've been researching how to naturally take care of digestive issues, like using ginger etc. Any precautions? I keep reading...ask your doctor before detoxing etc. My gastric bypass doctor seems to be too busy to handle my issues.
