I second the predrafting and then then the park and draft. Predrafting the fiber means to stretch out the fiber so that it's thinner and you have smaller pieces of roving to deal with. I split mine lengthwise too.
The park and draft is when you spin the spindle, then "park" it by holding it between your knees and let the twist go up into more fiber. If you are getting too much twist, you have to let that tension creep up your fiber some so it's not so tightly twisted.
I hope this helps. It can be frustrating at first, but then it's so rewarding. A few minutes each day of practice-don't do hours at a time.
