well, you've been advised to knock it, which is advice i can get behind, but if you insist on continuing my suggestion would be a t-break of at least a month (i've taken plenty of breaks from even dope, WDs are bad but that's just the price you pay. end of story. also bud helps sickness tremendously) and then in all future doses potentiate with tonic water (containing quinine) 30 minutes before dosing, and 400mg cimetidine, 30mg dxm, 4mg chlortab and 220mg naproxen. keeps your tolerance down (result of the dxm (increasing the dose will not keep it down further so dont do that unless you want to robotrip instead of ope) ) and increases analgesia and euphoria very noticeably.
this all being said, seriously, be careful getting deeply involved with opiates. i'm in love, and i always seem to end up getting sick when i have the most shit to take care of. not to mention after so long you completely lose the opiate feeling you remember from the first while you did it, and it will never come back without doing dope. stay well brother.
