Weakness, lightheadedness (feeling faint) and headaches for almost 3weeks

[Chase_25]

I'm 25yrs old. three weeks ago, the night(sunday) after i came home 3am in the morning and had 4x beers and 6x cigarettes(just started smoking this year for about a total of 70-100 from jan till now) and dancing all night, at 6pm through 11pm, i was hit by lightheadedness to the point that i feel like fainting. (Note that i woke up and ate at 12nn heavy lunch, 2pm junk food and orange juice, then 4pm heavy dinner). Went to the ER and was diagnosed with GERD, was given an iv of pantoprazole and i was kind of ok within an hour with light sleep. Next day, monday to wednesday, i was so weak and and was having lightheadedness episodes throughout the day with headaches that was like a minor pressure in my head. Come thursday, headaches were either nonexistent or very minor, so i came to work to friday. Saturday, i was kind of ok, 2nd week sunday, woke up weak that my voice was weak too, and maybe because I'm going to the internet searching for symptoms but i think my leftside is weaker, though im not weak to the point that i cant lift or push or do activities. went to the hospital 2nd week monday for a check up with a doctor, had bloodtest and chestxray, also went to an optha, and said that i was fine with a .25/.25 prescription for glasses to see if my lightheadedness would go away if i wore some glasses. went back on 2nd week wednesday, doctor saying my blood and xray were normal and said to follow up with a neuro if my lightheadedness still persists, said that it might be anxiety which is causing my weakness and lightheadedness. 3rd week sunday to 3rd week tuesday, waking up normal ish but as i get ready for the day and go to work, my weakness becomes more pronounced,lightheadedness sets and i feel like ****, after eating lunch it fades and sometimes sets in again by eveing, also have had this dizzy spell that happened 2-3 times where i get hit with this major dizzy episode for 1-3sec feeling faint and weakness in the limbs, was lifting this empty small bag and it suddenly felt heavy for a moment. 3rd week wednesday, present, still the same weak, lightheaded morning, braved through it but as i was on my 3rd spoon of food,got lightheaded that i had to sit on the couch and lay 8n bed for 2hours, am freling a bit ok now, but i don't think I'm getting better as time passes by.  Dont have money yet for a check up wih neuro and still saving for the glasses.

Note that for three weeks till present i am having weakness, lightheadedness, feel like **** when i wake up till i eat lunch, headaches. Is this because of GERD alone, or something else? As im not experiencing heartburn or coughing or burning sensation in the throat. What is this... im so scared..

Have the Dr check your fasting blood glucose levels and A1C.

Dr checked for those as well as thyroid, said that my blood was normal.

Great. Try not to fret too much. Make that neuro apt and go from there.
