Insomnia Treatment in Plano, TX: Getting to the Root Cause of Poor Sleep

If you’re lying awake at 2 AM staring at the ceiling, you already know that insomnia is miserable. What you might not know is how serious the downstream effects are — on your mood, your immune function, your weight, your heart health, and your cognitive performance.

Chronic insomnia is not just a lifestyle annoyance. It’s a medical condition. And like any medical condition, it has causes that can be identified and treatments that actually work.

At Sophia Rahman MD in Plano, TX, we take a comprehensive approach to sleep — one that starts with understanding why you’re not sleeping, not just handing you a prescription and sending you home.

Why You Might Not Be Sleeping: Common Underlying Causes

Many patients come to me after months of poor sleep, having tried melatonin, sleep hygiene apps, and everything in between. The problem is that these generic solutions don’t address what’s actually wrong.

Some of the most common causes of insomnia I see in practice:

Medical conditions

Thyroid dysfunction (both hypo and hyperthyroidism disrupt sleep)
Sleep apnea — often undiagnosed, especially in women
Chronic pain (arthritis, fibromyalgia, neuropathy)
GERD and nighttime acid reflux
Heart failure causing orthopnea (trouble lying flat)
Restless legs syndrome

Psychiatric and psychological factors

Anxiety and generalized anxiety disorder
Depression (which often manifests as early morning awakening)
PTSD and hypervigilance
Conditioned arousal — when your brain has learned to associate the bed with waking

Medications and substances

Certain antidepressants, corticosteroids, beta-blockers, and decongestants
Caffeine (more persistent in the body than most people realize)
Alcohol (disrupts sleep architecture even when it helps you fall asleep)

Hormonal changes

Menopause-related sleep disruption (hot flashes, night sweats)
Thyroid imbalances
Cortisol dysregulation

Our Treatment Approach

Initial Assessment

We start with a thorough evaluation — your sleep history, medical history, medications, lifestyle factors, and any symptoms that might point to an underlying cause. In many cases, we order labs to rule out thyroid dysfunction, anemia, or other contributors.

Lifestyle Modifications

Sleep hygiene is a starting point, not a solution on its own. We review your specific patterns — screen exposure, caffeine timing, sleep schedule consistency, bedroom environment — and make targeted recommendations.

Cognitive Behavioral Therapy for Insomnia (CBT-I)

CBT-I is the gold standard first-line treatment for chronic insomnia according to the American Academy of Sleep Medicine. It’s more effective than sleep medications long-term and doesn’t carry the same risks. We guide patients through the key components: stimulus control, sleep restriction, relaxation techniques, and cognitive restructuring.

Medication Management

When medication is appropriate — for short-term insomnia, or as a bridge while CBT-I takes effect — we prescribe carefully, using the lowest effective dose and monitoring for side effects and dependency risk. We avoid sleep aids that are inappropriate for older adults and review all existing medications for sleep-disruptive effects.

Regular Follow-Up

Insomnia treatment is not a one-and-done conversation. We track your progress, adjust the plan, and make sure we’re actually moving the needle — not just checking a box.

When to See a Doctor for Sleep Problems

You should make an appointment if:

You’ve had trouble sleeping 3 or more nights per week for more than a month
Poor sleep is affecting your functioning at work, at home, or behind the wheel
You wake up unrefreshed even after a full night in bed (this may indicate sleep apnea)
A bed partner reports that you stop breathing during sleep or snore heavily
You’re relying on sleep aids — prescription or OTC — regularly

Sleep problems are real and treatable. Schedule a consultation — let’s figure out what’s keeping you awake and build a real plan to fix it.
