Fumaderm has been a complete life saver for me! I am currently 99% clear (and please God I stay that way) However, Fumaderm can take quite a while to kick in. You start on a low dose and build your self up to 6 (blue) tablets a day. At the moment I only take 4 per day as I can't tolerate the side effects on 6. Stomach cramps, hot flushes, sickness, headaches....however, the side effects do lessen with time but they come and go with no warning which is a bit of a problem sometimes but for clear skin its worth the pain and discomfort on occasion. I was on a combination of Ciclo/MTX then MTX/Fumaderm my side effects were dangerous on Ciclo and MTX so I was weaned off the MTX fairly quickly and remained on Fumaderm. It probably took approx 4-6 months for me to clear completely. I was going to throw in the towel on more than one occasion but Frost another member on here who has also had excellent results on Fumaderm advised me to stay with it. I did and my skin improved fantastically. Can I say when I started on Ciclo I was around 90% covered, by the time MTX and Fumaderm were introduced I was still around 65% covered so, like I said, Fumaderm has been a miracle for me!
If you search on Fumaderm or Fumeric Acid you will find quite a few threads on it. I did blog my treatment however, one fine day I hit the wrong button lol and deleted a year's worth of ramblings!
Stick with your Fumaderm and let me know how you get on. What is your dosage at the moment?
