I am a licensed registered pharmacist. Regardless of the LSD you did that night, your symptoms are not normal. I think you need to see a doctor as soon as possible. I would write down everything you want to discuss with the doctor AND a detailed list of dates, times, and what you were doing when these episodes occur. Don't know how old you are or what type of insuranceyou have. If you need to start with your primary care physician, schedule an appt immediately. Keep in the back of toyr mind that you really need to be evaluated by a neurologist. If your doctor does not give you a referral, tell him you really need it to have "piece of mind". If he suggests psychiatry (usually because alot of docs don't know what to do and use this as a catch all solution), tell him that may be a good idea for the future but right now you need to see a neurologist. Hopefully, most doctors will want to give you a referral without even asking.
With respect to neurology, check on this board to see if anyone has a recommendation for a good neurologist. If not, ask family and friends. You can also ask your general practitioner for the name of a doctor. If still no one, I would go into a local pharmacy early on a saturday or sunday (usually not so busy) and tell them you are experiencing problems for the first time and do they have any recommendations for a good neurologist. Go to an independent pharmacy, or a place where you observe pharmacists interacting with their customers. Many times pharmacists have formed opinions over the years of great and horrible doctors as they interact with people often (I know I have). This would be a good yet more anonymous path to take.
Do not,let any doctor look at you strange like it is all in your head or start scolding you for trying an illegal drug. Tell the doctor up front about the LSD. If you sense the physician is passing judgement or just wants to give you prozac (go wuth your gut feeling), than see another doctor til someone takes you seriously. Doctors are only human and sometimes they pass judgement which can cloud their response. You'll find a good one if you try.
Finally, if you are actually still reading this, you really do need to seek medical as soon as possible. The symptoms which you are describing may or may not be very serious, but they need to be evaluated by an MD as soon as possible. Good luck
