i think it's a good alternative for people that need immune suppressants to have a long term.. not for hay fever or cat hair allergies.
i've used prednisone for chronic bronchitis a couple of times and once for an abdominal infection. the belly weight gain you're referring to is usually a shift of weight from the butt&thighs to the belly. i gained weight in the end, but only because i had become way too skinny dealing with the bronchitis for months on end. sure prednisone can be dangerous, but chronic bronchitis was way more dangerous in my case. i came pretty close to dying.
would i try worms? hell no.
