I've been under Humira since January. My symptoms improved very very quick, no more toilet runs and I am eatling many types of foods.
The doctor decided to increase the dose to once per week since I have a small fistula that won't go away. I must say I am very happy with Humira, the only downside was putting up weight. I guess more kilos are a blessing though ... I used to weigh 100 kg, and suddenly dropped to 70 kg in 3 months. That was really scary. Now I'm back to 100, fat'n happy
Hope it helps!
