Time lapse in between medications?

Depends upon your dosage of each drug. Also your tolerance - how long you have been taking your current dosages.

I am able to take my 1 mg of clonazepam and 100 mg of Tramadol at the same time with zero adverse effects. 1 mg of clonazepam is equivalent to 10 mg of Diazepam / Valium.

You must also take into consideration all other medications you are taking, not just diazepam and Tramadol.

If you are still uncertain, consult with your pharmacist as taking certain medications with Tramadol can increase your risk of seizure.
