It could be normal or it could be trouble to come. Like I said, I've taken many medications and it was never a good thing when I had a bad reaction right off the bat, at least for me. It tended to be better for me (and this is just ME) long term if I had NO real side effects, other than maybe mild fatigue, at the beginning. On the medications that made me hyper, things only got worse.
You will have to wait and see. Sometimes it was two weeks before side effects were intolerable for me, if they were going to be intolerable, and sometimes it actually was after the medications had been in my system for three months that I'd suddenly get toxic and start to hallucinate. Going off the medications was as difficult as being on a bad one, so be careful of that too. Removing an antidepressant causes a withdrawal effect that can be seen as needing the medication. It is not simple! This drug is not like stimulants where it is pretty easy to discontinue with no bad effects. Antidepressants are difficult for withdrawal. Straterra is an SNRI antidepressant, in the family of Effexor, I believe (could be wrong there).
