Is it out?

I am pretty sure I have a tapeworm.

For a year I've been struggling with constipation and unexplained weight-gain. I ate nearly nothing (no appetite, yet sometimes extreme cravings) and exercised rigorously every night (despite very low energy) and just couldn't get rid of my large, distended stomach.

I began my parasite cleanse three weeks ago. I've been on a raw diet and taking cloves/black walnut hull/wormwood three times a day. The results have been amazing! I have lost almost 10 pounds and my stomach is noticeably flatter. I feel like myself again. My energy is back!

Here's the question, though: I have passed large, pumpkin-seed shaped eggs and stools covered in what looks like white rice, but so far, NO WORM! Twice I saw thin 4-inch long white/clearish worm-shaped things, but I think it was just mucus or the tapeworm's skin. HOW DO I KNOW IT'S GONE? Will I definitely pass something that looks like a large worm? How much longer should I remain cleansing with the cloves/black walnut/ Wormwood ?

I know that's a lot of questions, but there is also one more: I am going to a gastrointologist in a few weeks, should I have him prescribe me actual drugs for this thing? Are the side effects very bad?

I would really appreciate anyone's insight. THANKS so much!
