I gave you a lot of options. But to focus and get the bull by the horn the best thing you can do is drink Lassi twice a day and eat fruits. Lemonade and raw fresh coconut water will be best for you.
Yes, it would help if you take enzymes and probiotics. For your migraines take magnesium 400mg twice day. Then when migraines are gone you can take 400mg everyday. Get a good, reputed company MG, there are lots of inferior products on the supermarket shelves.
13 days after a fast and you are still feeling the effects of dehydration. Are you at all unable to focus or delirious? If that is the case then check yourself in ER. They will put you on an ivy, but I would not take any drugs.
BTW, falafel is hardly healthy. It has double fried chick peas, which is dead food with toxins from over heated oil, and pita breads are also not healthy. Stick to salads with olive oil and lime or lemon juice dressing.
