I am not going to lie its going to be more than just two days feeling like hell. Try two weeks. BUT!... I will say that this cycle you speak of (the one i have been in many a time) is completely breakable. Log on here everyday. Post... read... see other people making progress and struggling with the same things. Set miniature goals. Say oke i am going to at least try... no DO 15 days clean... See how you feel after 15 days and say hey i think i am on the right track i will give 15 more days ago. Before long (for me about the third week) I began to realize that i won't be depressed forever without opiates. And that life is beginning to fill me once more. I wish you so much luck and i hope you give us daily updates. We are all here with you and i really suggest reading my, bfd, 1dayatatime, and Olivio's posts. If you read our day 3 posts vs our day 16 posts you will see that progress comes DAILY, and more importantly that progress just comes in general. good luck
