i was extremely tired and a lil high the first few days. the 2nd week is when i felt back to the old me.
Could be part of the adjustment period, as it's normal to experience mild w/d like symptoms for about the first week, but like IBK said, definitely call your prescribing doc. Your dose may be too high, or too low.
Calculating the induction dose for Sub is not an exact science, it's not abnormal to need some minor adjustments in the first few days.
You should call your prescribing physician and explain your symptoms. It may be that your dose needs to be adjusted. Let us know how you make out.
