I Have Been Self Treating My Self With Suboxone For

I have been self treating my self with suboxone for the past year or so..i cut a 8 mg stip into 4 pcs. I take one pc daily normally around 10a.m. or when i feel as though im sick ..it feels like im in a state of medicine head not myself then i take it..if that makes any sense and within an hour or 2 i feel normal again.. and only sometimes in the evenings if i am feeling very tired or sluggish i will take a 2nd pc. from what ive read this stuff is suppose to last a long time in your system but the next day at around 11 a.m. i get that disoriented feeling again. Am i takeing enough? I have decide to see a doctor to get these legally but that appt is may
