Soda tasted funny after about 12 hours. This either eventually goes away, or you get used to it. I drink a diet soda every day and don't notice it tasting any worse than it normally does.

I think the first time I was on it I felt a little woozy within a day or so, and it lasted a couple days every time the dosage was raised. I was started on 25 mg, increased by 25 mg per week.

I had a little bit of problem with vision at 300 mg, but I was doing photo correction at a printing company. I don't think I would have noticed it otherwise.

I am on 400 mg now with no problem other than I want to drink ice cold water all the time.
