Contrary to the package inserts and clinical trial data, I had horrible side effects, Tremor, fatigue and exhaustion but unable to sleep, as well as what can best be described as a feeling similar to electrical shocks in my brain at random time. I called them my little "mini ECTs".
I gave it a full two months because having had experience with various antidepressants and other psychopharmaceuticals, I know that side effects take on average two weeks to a month to go away and the patient doesn't usually see noticable improvement until at least 6 weeks into treatment. After two months with no abatement in my symptoms and still experiencing the horrible side effects, I made my doctor wean me off of it (very important, as going off it cold turkey causes even nastier side effects than I was experiencing).
Of course, the beauty of these drugs is that they work differently on every person, so just because I had a terrible experience with Strattera doesn't mean that you will. I do think it's important to be told all the potential side effects so that if you develop them, you know what's happening. The literature on Strattera did not list many of the problems I was experiencing and I had make a few anxiety-ridden calls to my doctor to before I understood what was happening to me. When you have neurological issues along with depression, it can be very disconcerting to have side effects from the medication you take that are also neurological in nature. It makes it hard to differentiate between the disorder and the medication/side effects. So if you decide to try Strattera, just make sure you read everything you can about the drug. Remember, it's your brain your messing with.
Here's a great site that has great user feedback on different drug therapies for various ailments. I found a quite a bit of useful real life information on this website. Here's their link for Strattera:
