I've used flagyl many times to good effect on my snakes, it's actually fairly safe and hard to overdose your snake if you can follow directions. I personally don't think probiotics are worth a damn for snakes.

That much weight loss is really not that normal, and green poop is really not normal either. I would recommend a vet visit. You're vet can give you the correct dosage to use if they think flagyl is the correct med for your snakes problem.
I know flagyl and I know pro-biotic. I'm new to snake owning didn't know which was better for the snake. Her green poop was one time dime sized and after that a huge normal poop. She hadn't eaten since oct 8th, till i did some trickery 2 days ago and offered her a gerbil, tagged and swallowed in 45 seconds , Thank you for your reply.
