I started taking both last week and I think I am on to a special combination.
But first, before I tried both, I previously had taken 5mg of modafinil once a day (for a few days) and the effects were not great. I'd feel slightly more awake but it seemed every other aspects of my mental state was unaffected. I'd have a crash after several (6+) hours and feel very tired. My doctor then prescribed strattera and I started taking the smaller 18mg doses from a sample trial pack strattera gives out. Again, not much success by itself. Strattera made me feel very tired and zoned out. I don't even know if there were any benefits.
Amazingly, I noticed that the two drugs combined make me feel pretty damn good. Motivation is up, and I feel considerably more awake (especially noticeable is how I do not feel tired after a big lunch), and I can concentrate for longer. During conversations, I'm more engaged and a better listener. I play games such as ping pong and notice my reaction time is improved. The most amazing aspect of the combination is that the effects last almost the entire day. I usually take both around noon and I'm good until 11/12pm at least. Overall I'm very satisfied to have found something that works over several hours at a time and without any major swings or drops in efficacy.
The only downsides is that I feel a little too wired for the first several hours. I know my heart rate is slighly up by 5+ bpm too. I also experience the common side effects of dry mouth and nausea, and am not sure if they are going away significantly.
I'm also little concerned that the strattera sample pack I have is designed to ramp up in 4 dosage sizes from 18mg to 60mg. Considering how I feel 18mg is already quite powerful, I'd rather not continue to a higher dose.
notes: I'm a lighter guy, mid 20's, with history of mild depression.
