Good job so far. For mouth soars, take half a cup of water and mix with half a cup of H2O2 (Hydrogen-Peroxid) and swish and spit out the water. Do this three times a day.
Anti-inflammation pills? Seriously? After a fast you will not need any pills. Best Anti-inflammatory thing on the planet is Turmeric powder mixed with black pepper. 1Tbsp Turmeric mixed with 1/4 Tbsp Black pepper every night before bed will give you a lot more than you can imagine.
7 more days will be easy if you drink warm water as per thirst.
