100 grams of carbs shouldn't be too bad. Most low carbs try to keep you under 20 grams if they don't give you PWO carbs. The more you restrict yourself the more results you probally see.

1700 grams of carbs is fucking rediculous! My reload days were something like 600 grams and I thought I was going to pop. Fruit juices should help get you near that along with sugary cereals which usually contain alot of dextrose. The Reporter (RIP) turned me onto gummy worms as a snack on the carbs day, a little bag contains a huge amount of carbs with no fat. Stick with Lyle's suggestion and mix up sugary sources and low-GI foods, otherwise you will probally feel sick as hell at the end of the day.

Ohh and on the low carb days I would suggest using Metamucil or some other fiber supplement. It will keep things moving and if your using alot of oils for healthy fats it also helps keep things together so your not blowing your ass off. I had to learn the hard way :eek:
