I can only sleep a couple of hours a night

I was on anti depressants which one of them was a sedative which helped me goto sleep. Ive been off them for a month. Now it seems I can only sleep a couple of hours a night . Even though I feel tired. I have aspergers. Ive always had trouble going to sleep but normaly once I did I never woke up so quickly. Im not sure what to do? Maybe keep going like this and it will improve? Should I goto the doctor? I dont really want to take sleeping medication.

You could give it a few days but if it doesn't improve, ask your doctor what you can do. Maybe there's a good "soft" remedy that can help you.
