Hi.
I have been on both in the last couple of months. Both had there advantages and disadvantages. The cyclo I slept about 16 + hours a day on but it worked immediately and got the best results. However I developed an allergic reaction to it so I had to be taken off them. The MTX I have just finished after 2 doses as it made me too sick to continue, couldn't eat, although did have loads of energy.
However as someone else said, not everyone gets bad side effects. Everyone reacts differently, there is no telling what will work and what wont I am afraid...you are just as well tossing a coin.

The disadvantage (in my opinion) with the MTX was not being able to drink, which is fine in a normal week but personally I would have found hard in the long term socially, but this may not be a problem for you.
Good luck in what ever one you try, and keep us updated.
