I never had a problem with rebound from Butalbital and I used it a lot. I did feel like I could've gotten addicted but once the drug cleared my system after a few days I forgot about it. There is so much caution about rebound from Butalibital it scares people into not using it. I had migraines so bad that I finally just ignored all the warnings and took what I needed to keep going. Now I don't get them anymore and I am fine!
