When to take it depends on you. Some people take theirs in the morning some at night. Depends on if you have any side effects. As the days go by, try morning, afternoon, then night. Once you find a time frame that works for you, keep it at that time. For instance if the meds make you tired, take at night. If meds make you hyper, take in the morning. If they give you stomach problems take at night. You get the idea.

I take mine at night because they help me sleep since it promotes tiredness

I like staying on an early morning schedule taking my meds..I have changed my thought process with this so I take them every morning..religiously..

In my experience most the medication I take makes me drowsy. So I usually take it in the evening

Normally you take it as per doctor tells you at meal time just make sure you take it.
