I'm 26 and I have Crohn's disease. I went through a fantastic period at the start of the year where instead of taking 4 pills a day, I injected myself once a fortnight. The side effects, unfortunately, meant that I had to stop taking them.
Now, I take about 6 or 7 pills every day! I'm about to go onto another similar medication as well, though it requires a day in an infusion suite every 8 weeks instead. The pills are now mostly vitamins, but also something to deal with the side effects of that drug I was taking.
I enjoyed the respite while it lasted!
