Hi Pizzabase,
Keep going with increasing the dose, if you can.
I started on Fumaderm in December 2010. I was pretty well covered in P until February 2011 when it started to get much better. The most annoying side effect that I have had is a continually runny nose. Other side-effects have come and gone.
There is a thread on this site called "Fumaderm how long does it take", which pretty much documents my experiences (and those of other people). All I can add is that, for me, Fumaderm has been the best thing since sliced bread.
Regards,
Daryl
