I did take the 150 mg extended release last night and feel pretty "in the middle" this morning... I'm assuming that's a good thing! I haven't had the urge to clean my entire house within 1 hour of waking up so that's nice. I'm just sitting and enjoying my tea. My mouth feels a bit thick and dry but that's the only real side effect besides mild sedation. It will be interesting to see how I will work out the extended release with working nights. The nights I work, I 'll have to take the extended release in the AM when I go to sleep and on my days off , switch back to taking it at night.
