The most common though that I see in BJJ is the cervical sprain or strain. The cervical spine is the most mobile segment of the spine however it puts it at a high risk of injury. Cervical sprains/strains are soft tissue injuries. A strain is linked to muscle, while a sprain is linked to tendons.
However, for some people, effects are much shorter and they have to take modafinil 2X per day (albeit this is not that common). For other people, effects can last 20-24 hours. It all depends on how your body processes it.
Since Adderall is an amphetamine, the length of time it is detectable in your urine will depend upon the type you are using and the frequency of your use. If you are taking Adderall instant-release, it will stay in your body for approximately 35 hours. This does vary due to individual body type and habits.Using Adderall XR (extended-release) will cause it to stay in your system for approximately 60 hours.On average, all amphetamines will clear your system in about 72 hours. This does depend on what type of testing is being performed.harmacists in general consider after 3-5 half-lives, about 90% of the drug is cleared from your system and no longer has an effect. Hence it takes 3-5 days for Adderall to get out of the system.
