I take 350 mg at night and 3 25 mg through out the day. I started on low dosages about a year ago and slowly worked my way up. I've been on this amount for about 3 months. My side effects are: grogginess, stuffy nose, slight constipation. The grogginess only happens at night and wears off when I wake up. I do have to give myself about 9-10 hours of sleep lol. I just can't get myself up before 9 hours from this dose but its okay for me right now. I have to force myself out of bed but after 5-10 minutes I'm awake. The 25 mg pills at first made me tired but I soon adjusted to it. I go manic easy and have chronic sleep problems so I need higher doses.
