Methylpred DP and antibiotics

Persistent pain in upper stomach. No matter what I eat or drink, it won't go away. I've researched the net and it seems my digestive flora is disrupted. Here's what I've found:

"If you do need to take antibiotics, make sure to support your liver and keep it as strong as possible. Every drug we take has to be broken down; it's the liver that does that for you. Eat dark-green leafy vegetables like kale and collard greens, as well as broccoli, beets and artichokes to keep the bile flowing. To regenerate your liver cells, take milk thistle supplements.
To keep your gut healthy while you're on antibiotics, get good bacteria into your system by eating goat's milk yogurt, drinking kefir (or kumiss, or koumis) or taking probiotic supplements.
About yeast overgrowth, ... castor oil, green tea extract and yogurt could be of help. Once more, before taking any action please consult a physician.
Milk, milk products, alcoholic beverages, tea, and coffee cause indigestion in some people because they stimulate the stomach's production of acid.

Yesterday my doctor prescribed the dosepack for reaction to a tic bite that wouldn't clear up on antibiotics alone. He also thought it might help my chronic sinusitis. My sinuses are better and my knees which have a little arthritis also feel pretty good. The rash from the tic bite is slowly fading already and I am only on the 2nd day of 6. My only problem is the night time dose. I woke up feeling anxious several times last night and my legs were twitching. I am not looking forward to this evening's dose.
