I know how tempting that is but steroids can't be started and stopped like that. The doses must be lowered slowly or it can mess up the chemical balance in your brain and cause many more problems. I am not sure what dose the doctor has you on but talk to him/her about how you are feeling and let him/her know that you want on the lowest dose possible while still helping you. If you decide to go off of the meds you MUST do it with the help of your doctor and reduce the dose slowly over time in order to not damage your body.
Hope that helps!
