Diet pills.

So I started to work out recently every day. I have also started to drink a bottle of water mixed with apple cider vinegar and lemon juice from a lemon every morning and night. I would like to try a diet pill as well but idk what to try. I know many people are going to tell me not to take it and what not but I’ve thought long and hard about it and I want to try it out. I know my body well enough to know when something isn’t good for it so if I feel like it’s not I’ll stop immediately. But I want a somewhat cheap one, please help me out.
