hi desi,
i take 400mg three times a day and i was tired at the beginning but got over it pretty quickly. make sure you space it out well ... and yes the epson salts and the heat are great.
good luck to you with it all.
i have a 14 year old grandson living with me and my husband gets him off in the mornings too. don't feel guilty, you can only do what you can do ... so just love them after school, that is what i do! joan
