To be honest there may be hope. If you were to start eating right and exercise. Join a gym if need be. What your system would have to do is build up its immunity and the only way to do that is be able to absorb the nutrients thru you stomach. What it takes for that to happen is you need lots of enzymes so that you can break down food is the fastest passible way. Also going on a puree diet would help also and grazing throughout the day. Never eat enough to get full because you have to keep your system flowing. Dont allow food to become spoiled in your system. Exercise is good because the more oxygen supplied make its worse for candida to survive in. Be sure to buy enzyme supplements and foods that contain cultures. Do no take cultures within a couple hours of taking enzymes of you will aid in there destruction. You could implant asidopholis pills in small pieces of veggies to help get them into you intestines. Also Oregano worked for me so a pill or two a day could benifit you also if you can tolerate it.. Since you cant seem to take what you have been taking cut back or take on an every other day or more basis till you can tolerate.
Reason i suggested exercise is because a couple years ago i was going to the gym for about 8 months and felt better than i had in a long time, Hardly any reactions in that time. When I stopped I started to get worse again. At that time I wasnt taking anything at all other than watching what I ate.
