Cheyxox the subs are meant to relieve w/d symptoms. From what you said I think you put yourself into precipitated withdrawals. Google that if you don't know what I'm talking about.
You have to wait until your almost into fullblown w/d's until you take your suboxone dose. Usually 24-36 hrs, but depends on your dosage and amount of time you've been on fent's.
I agree with Maylie. Sounds like a very high dose of subs in a day and it's no wonder your feeling quite sick. You should be much better by the time I hear from you again. Then we can go go into sub usage after things calm down.
Best to you. Talk soon.
