Ever since I started taking Diltiazem I haven't been able to sleep more than 3 hours at night.
I checked for possible side effects and sleep disorder is not listed as such.
Even if it is not listed it could still be a potential side effect, I suggest you contact your Dr. and inform him / her about it.-
Insomnia can really get to you, I suffer from it so I understand how you must be feeling.-
List of possible side effects for future reference:
Undesirable effects of Diltiazem include hypotension, bradycardia, dizziness, flushing. It's quite possible,however, unlikely unless you notice you are experiencing the above symptoms when you awake.

I have been a sleep tech for >17yrs and have never had a Patient relay this as a "side effect" of Diltiazem, if anything quite the opposite with c/o excessive lethargy being very common. However, this is not to say that your "reaction" to this medication may well be an "allergic" one an I would definitely consult your prescribing physician. Maintenance insomnia is a very cruel and frustrating thing and maybe this channel blocker may not be the one for you. Good Luck and hope you find a solution soon as well as some restorative sleep.
