I take Adderall daily (90-120mg IR) and have used Focalin on many occasions. That being said, Focalin gives me more of a "tweak" experience lasting at most 2-3 hours, whereas with addy its a less intense experience, lasts quite a bit longer (6-8 hrs depending on dosing) and not as quite a "speed" like feeling. So, if it were myself, then yes I would easily be able to sleep having taking Focalin (even at a high dosage). However, dif meds effect ppl differently so this may not be the case for you. As for Benedryl, I sometimes take my addy a little late and have an exceptionally hard time sleeping. In this case, my first solution is to take some benzos i.e. alprazolam (not a recommendation simply personal experience). If none are available, I take a high dose of Diaphenhydramine (Benedryl) along with a very high caloric meal, 1000mgs of Vitamin C, plenty of water & a hot shower. Natural sleep aids such as Melatonin will indeed aid in the process, but as to alcohol, I personally wouldn't go that route. Finally, it'd be worth a shot (IF it were me). Most importantly, be careful. Also, the alcohol isn't a good idea IMO.
