Have you tried searching for "help getting off
amphetamine pills" on google? I did that and it came up with some stuff that might be helpful. I know we are not supposed to post sites so I will let you do the search yourself, but please don't give up. Keep searching for help. I wish I could help you more, but maybe reading the experiences of others who got off of it will help you more than getting advice from those of us who have never gone through the pain of what you are facing now.
You've taken the first step - admitting that you need help. I say good for you. Keep it up!
