Thanks a million for your quick/comprehensive reply and for the cogent advice/comments therein. I'm glad to inform you that I managed to find an organic protein powder. I’m planning to add some spirulina powder to each and every shake. As you might know I started to wean off my medicine since a while. From tomorrow onwards I will stop my Prednisone. Imuran will be weaned of within the next week. God bless and once again thank you very much for your advice.
