Yeah, I have absorption probs too.I never noticed the lines in my nails... I just looked and wow! I have them! I remember ridges when i was younger, but i think i am doing better lately... I am taking liquid vitamins and eating well. I certainly twitched when i started a parasite cleanse... I don't know if it was from the herbs or hte critters. At any rate, I am on day 29 now and feeling great, so i know you cna do it too. I drank red clover ttea to help with any uncomfortable symptoms. Best of luck, and keep us informed of your progress!!!!
