It does take time for the withdrawals to stop. OTC meds will help with them. Exercise and baths will too. Goo luck to you and you will feel so much better not relying on pills anymore
I will even suggest that the "withdrawals" are in your head, not physical, because you haven't really quit anything.
So, you are taking an opiate to quit an opiate... Both those pills are basically the same thing. You are just quitting one brand name and using another.
Just quit the opiate period.
