Welcome to the forum and the wonderful world of snake keeping!!
In order to help you we'll need more information.
Let's start with the snake.
-Is it a juvenile? Adult?
Now tell us about your setup:
-what type and size enclosure are you using?
-how are you heating the enclosure?
-ARE YOUR HEAT SOURCES REGULATED BY A THERMOSTAT??
-how are you measuring temps and humidity?
-do you have hides? water bowl? fake plants?
Now, how about feeding:
-what size prey are you offering?
-how often are you offering?
-how are you heating the prey?
-what time of day are you offering?
And lastly:
-how long have you had the snake?
-are you handling the snake?
-is the snake's enclosure in a high traffic area in the house?
I know it's a lot, but the more we know the more we can help you out.
