I read your question carefully and I understand your concern. I do not think you need to worry about Ecosprin AV, it contains aspirin and atorvastatin which neither have any negative effect on sleep, so the cause is not there. Often factors like anxiety might be at play. You should try regular sleeping hours, avoiding sleep during the day, exercising, avoiding stimulants like caffeine in the evening. Herbal remedies like chamomile tea might help as well. If those measures do not work there are medications as well (zolpidem melatonin etc), but should discuss the problem more in detail first (type of insomnia, causes, accompanying conditions etc) beforehand in order to pick the right option. I hope to have been of help.
