The likelihood of getting pregnant right before your period is extremely low. For women who have a typical cycle of 28 to 30 days or longer and their cycles are regular, it is fairly safe to say that your ovulation occurred between Day 11 and Day 21. The egg is only available for 12 to 24 hours for conception.
Figure that a single dose of Adderall (any size) takes about 20 minutes to kick in (allow 30 minutes for time-released Adderall XRâs). The âhighâ peaks at about the 1:30-1:45 mark (that is, 1.5 hours since it kicked in, so about 2 hours since you took the pill).
Answer Wiki. It depends on a variety of factors such as your tolerance, the type of Adderall you're using (regular or extended release), how your body reacts to the drug, your physical health, age, tolerance level, etc. It can last anywhere from 4 hours to 12 hours. For people with ADD, Adderall can be a life changer.
