Hey
@Bag84
Basically, what you're describing is a phenomenon known as the "Kindling Effect". The nomenclature is generally used to refer to sedative-hypnotic drugs like Alcohol and Benzodiazepines, but it's my firm belief that it is a more general phenomenon associated with being dependent upon drugs, not just sedative-hypnotics.
Most people who use Opioids won't develop any kind of withdrawal syndrome until they've been using for weeks or months. With Benzodiazepines, I feel this process happens a little more quickly. Once you have developed a tolerance and withdrawn, it is typical for one to develop a tolerance more quickly and for that subsequent withdrawal experience to be more severe. If I were to use Heroin for 3-4 days right now, I would expect a nearly full-blown withdrawal syndrome.
So yea, I think that you're just becoming re-dependent upon these drugs every time you pick up your prescription. You're not alone in this. It's pretty much universal from what I have read and experienced. It's one of those things, however, that "mainstream" medicine is not going to focus on along with stuff like Post-Acute Withdrawal Syndrome. Side-bar, I'm pretty sure that if PAWS and its true nature were understood by people, the whole 30-90 days rehab rackets would be bankrupt nearly overnight i.e. they can't actually fix you in such a short time.
