We can't tell you what medications are going to be helpful for you, as everyone's body is different. Lorazepam (Ativan) and Alprazolam (Xanax) are shit hypnotics (pharmacological agents that induce sleep), but are king when it comes to sedatives/anxiolytics (pharmacological agents that have calming/anti-anxiety properties) - Alprazolam is a bit better at equivalent doses, but more lipid soluble (shorter plateau/duration of action) and half-life (amount of time spent in blood). Diazepam (Valium) is good for both of these purposes (anxiolysis (anti-anxiety) and hypnosis (sleep - inducing) that is), but isn't as effective for anxiety as Alprazolam (and for some, Lorazepam (Diazepam actually works better than Lorazepam than me...you see where the issues comes from? It's all subjective.)). Temazepam (Restoril), Estazolam (ProSom), and Triazolam (Halcion) are great hypnotic (once again, sleep-inducing) agents still in use today, but have no use in day time sedation for debilitating anxiety.
In my honest opinion, Cyclobenzaprine (Flexeril) is a horrible muscle relaxant. I would personally try to have that switched to Carisoprodol (Soma) - first choice, Baclofen (Kemstro) - second choice, Tizanidine (Zanaflex) - third choice, or at the very least, Methocarbamol (Robaxin). Whatever you do, don't change to Metaxalone (Skelaxin); that is a horrible drug.
To help you out any further, I'd need more information on EVERYTHING you're taking (i.e. dosage (amount you're taking each time in milligrams or micrograms), frequency (how often you take it), and whether these drugs are scheduled (taken at a regular time every day or so many hours regardless) or if they are PRN (as needed every few hours) - for example, on that last bit, there's a difference between taking Norco 10-325 every 4 hours regardless of pain levels and taking Norco 10-325 every 4 hours as needed).
I will PM you this post so that you see it the next time you visit this website.
I've personally taken everything I've mentioned in my post as well as some others. These are my personal recommendations in the form of "Medication (Generic Name) - Frequency - Indication (reason why I suggested it):
One from each section (possibly 2 from the first at much reduced doses)
Xanax (Alprazolam) - TID or QID (3x/day or 4x/day) - Anxiety (Extremely severe, frequent, panic attacks) - (or Xanax XR (Alprazolam XR) - Q-AM or BID (Once or Twice Daily)
Valium (Diazepam) - TID or QID (3x/day or 4x/day) - Anxiety (General/Social anxiety with frequent, moderate intensity panic attack/doctor is uncomfortable with Xanax)
Klonopin (Clonazepam) - BID, TID, or QID (3x/day or 4x/day) - Anxiety (General/Social anxiety with the infrequent, mild-moderate intensity panic attack/doctor is uncomfortable with Xanax/Valium)
(Higher Dose) Ativan (Lorazepam) - BID, TID, or QID (2x/day, 3x/day, or 4x/day) - Anxiety (General/Social anxiety with the infrequent, mild-moderate intensity panic attack/doctor is uncomfortable with any of the above
Soma (Carisoprodol) - TID or QID (3x/day or 4x/day) - Muscle Spasms/Rigidity
Kemstro (Baclofen) - BID (2x/day) - Muscle Spasms/Rigidity (Doctor is uncomfortable writing for Soma, or Soma is too sedating)
Zanaflex (Tizanidine) - BID (2x/day) - Muscle Spasms/Rigidity (Doctor is uncomfortable writing for the two above)
Robaxin (Methocarbamol) - BID or TID (2x/day or 3x/day) - Muscle Spasms/Rigidity (Doctor is uncomfortable writing for the above)
ProSom (Estazolam) - Q-HS (at bedtime) - Insomnia (You have issues getting to sleep, staying asleep, and when you do get sleep, it's never restful)
Restoril (Temazepam) - Q-HS (at bedtime) - Insomnia (You have trouble getting to sleep, staying asleep, getting restful sleep, and your provider isn't familiar with ProSom and is uncomfortable with it besides it's great safety profile and greater clinical efficacy than Restoril and Halcion)
Halcion (Triazolam) - Q-HS (at bedtime) - Insomnia (Early waking isn't an issue for you and you just need something to conk you out)
Ambien (Zolpidem) - Q-HS (at bedtime) - Insomnia (Benzodiazepine hypnotics are just too powerful, but you need something that works very similarly)
Lunesta (Eszopiclone) - Q-HS (at bedtime) - Insomnia (Benzodiazepine hypnotics are just too powerful for you, but Ambien just doesn't do it even at 20mg/night)
Lyrica (Pregabalin) is also a good medication in terms of adjunctive therapy for chronic pain issues, anxiety, depression, and insomnia (though it only has FDA approval for the indication of Postherpetic Diabetic Neuropathy. It also potentiates (enhances) any GABAminergic drugs that you would be taking (every drug I mentioned in this post with the exception of Zanaflex (Tizanidine) and Norco (Hydrocodone/Acetaminophen - though, I only mentioned this drug in an example).
If I could dole out my own scripts I'd have Diazepam for general anxiety, Alprazolam for severe anxiety/social anxiety/panic attacks/PTSD, Carisoprodol for muscle spasms/rigidity, Estazolam or insomnia, and Lyrica for neuropathy/anxiety/depression/drug booster for my other drugs.
Please shoot me a PM when you get the one I send you and let me know how often you take how much of everything.
