I am psoriatic arthritis patient with back pain and si joint pains in addition to other joint pains. I use hcqs 200 mg for psa. Spine surgeon prescribed duloxetine 20 mg one in morning & one in the evening for my back pain. These tablets also reduce other joint pains and also helps in controlling my inflammation. But my problem is because of this duloxetine capsules my sleep has become very much disturbed and I am unable to fall asleep when I wake up in the night. I feel active all the time and suffering with racing thoughts/brain fogg. I am not able to calm my mind by all means. To counter this I added mythy cobalamin 750 mcg and 1/2 of clonotril - .25 mg. But still then I get up between 3 to 4 am and unable to fall asleep. Totally I am getting a sleep of about 4.5 hours to 5 hours a day. Increasing clonotril dose causing me irritation in the stiff muscles surrounding the joints. I tried magnesium supplement which worked nicely but it increased my scalp psoriasis rapidly. I tried all forms of magnesium but same results. Melatonin helped a bit but it causing tiredness during entire day. Could you please suggest any medicine to calm down my thoughts and to get a restful sleep? Thank you.
