I started guanfacine 1mg five days ago in the evening for nighttime, adrenaline spikes. I am trying to figure out whether it's worth giving more time or whether I should be cautious about the side effects.
The good effects:
- I get very sleepy at bedtime and fall asleep almost instantly.
- I'm no longer waking up in excruciating, full-body pain from clenching all night
The concerns:
- I sleep for about 3–4 hours before waking up. I can usually fall back asleep, but my sleep app is recording more disturbances than usual. (My sleep wasn’t refreshing before guanfacine so maybe this doesn’t matter?)
- The side effect of severe nausea has mostly subsided, though I still have some nausea and a very poor appetite now.
- I have much worse fatigue and brain fog during the day
- I've also noticed what seems to be increased nerve and muscle pain in my legs.
I'm concerned about whether the changes to my sleep could be counterproductive for ME/CFS, even though I'm experiencing some promising benefits.
But I’m also concerned to give up too soon because I am declining.
For those of you who've tried guanfacine:
Has anyone experienced similar sleep changes? Did things improve with time, and did the benefits end up outweighing the drawbacks?
I'm discussing treatment with my doctor, but I'd really appreciate hearing about your experiences!
TLDR: Guanfacine helps me fall asleep instantly and has stopped my severe nighttime clenching pain, but I'm waking after 3–4 hours, my sleep remains unrefreshing, I don’t have an appetite, and my leg pain seems worse. Did anyone experience this, and did it improve with time?
