Morning and night. When I was on 200mg, I just took it in the morning. Above 200mg, I split into morning and night. I always used to take it all in the morning. But at one point, I'd been bumped up to 400mg (in spaced +50mg steps from 300 iirc) and wow, that didn't work out(!) I had 2 significant side effects, but can only remember the wonky vision. Called psych right away. Next day switched to 200 in am, 200 in pm. Problem solved.

Currently on 300mg. Quite sure we'll be bumping it up again. Only side effects were a day or two with a light headache and body aches at the very beginning of starting on it, and just the single day of the ones mentioned above. In mornings I take after eating. I can be inconsistent with timing and have found if I dose too close together, I don't feel too well. (We're talking just a few hours between. Not on purpose(!) It's a matter of forgetting, as the mornings are so automatic). Can still do stuff, but it's an uncomfortable feeling for awhile till things are leveled out.

I've had a good experience with it (7, maybe 8 years). If anything, people tend to find it a bit activating. Drowsiness would be pretty unusual. As for dizziness, I've only ever found that to happen with the doses-too-close thing (but I'm on a fair bit, so...)

Can you take your meds before you go to work? Sounds like you're a little uncomfortable with taking meds there.
