Sorry, but BL isn't the place to ask about things like that... we're here to help you safely use drugs you might have already, not help you choose new things to get high on.
If you are "new to drugs" it probably isn't going to make you feel any better if you go and OD on over the counter drugs - there are not very many ones that will fix your troubles if you're feeling crappy, and many of them will just make you feel sick or out-of-it.
Maybe consider posting about your problems in
The Dark Side or
Mental Health forums? Or if you're feeling like you might hurt yourself or others, call for an ambulance or a mental health crisis line. Don't rely on rapid responses from the internet!
If you really really want to get high off over the counter drugs, do a little research to know what is available in your area - everyone's area is different - and
then make a post about whatever you have questions about.
I moved your posts to a new thread, because hijacking other threads to post off-topic questions isn't looked on nicely here. But unfortunately it's going to be closed.... sorry again!
