Hi and welcome to the GERD forum.
U may not want to hear this but smoking can be a contributor to ur problem...it is on the list of things besides spicey food to avoid...meds along with diet and lifestyle changes ( smoking) can affect the way u feel and if u continue to develope a persistant GERD issue.
Ask ur pharmacist what OTC med will be best for u....if ur problem persists please see a GI dr.

After dealing with my four month old girl with GERDS, I'd say you should try something over the counter for that, and if it doesn't help I'd see a GI Specialist. I tried many things with my little girl, but ended up going to a GI Specialist. How long have you been smoking, more than likely it's not the smoking that is causing the issue. I honestly think it sounds like GERDS, try something over the counter like prilosec. Good luck and I hope you are feeling better soon.
