Hi, I have had Crohn's for 24 years. I have been on every drug there is and have had 3 feet of my colon removed. Since 2009 I have been taking Humira. Since then I have had to have 15 units of blood and countless iron infusions. I have talked my doctor into letting me go off of Humira to see if it is the cause of my blood levels dropping constantly. I have to say it is has been 3 weeks and I feel amazing! I am sleeping better and have had zero panic/anxiety attacks. I would have them daily and I would only get on average 5 hours of interrupted sleep each night. I will have to decide which is more important, my sanity or my remaining colon when deciding if I am told I have to go back on Humira. Blood tests in 2 weeks to see if any improvement.
