I read your first post and like you have Crohns and hypoglycemia and find it really hard to go without meat at mealtimes. I'm not even gonna talk about the Sugar cravings... : ) I've done about 10 flushes so far, and each time my digestion and bloating gets slightly better.
I really think you should follow this flush up with an enema or even better a colonic. I too was very was constipated after my last flush but only back to back enemas were able get the waste/toxins out. Hopefully you should start elimating again the day after the flush.
I'm guessing the reason for the jittery feeling is due to the release of toxins into your system, but if the flush has worked you'll get a little relief from the hypoglycemia symptoms which is always good! But generally, you should find that you're able to get a good night's sleep in the following days after your flush.
