Hi! I'll be glad to be of help with this issue.
Valium and Klonopin are probably the benzodiazepines you would try. Triazolam has a much shorter half life and so may not have been as effective for you. The half life means how long it takes for half of the drug to exit your system. So if your system eliminates Triazolam at 3 hours (average half life) then it may not work for you as long and thus effectively as Klonopin which can last up to 8-10 times longer or Valium which lasts even longer.
But there are also antispastic agents that can help depending on your medical history. Baclofen, for example, is a muscle relaxant specifically. So that might be something to discuss with your doctor as well.
Okay, I wish you the very best!
