Chest pressure and breathing

[MendozatheJEW]

SWIM does not understand what has happened with SWIM's Adderall experience. At first he was calm, and motivated, normal feelings of goodness. Was using Temazepam as well to curve and feel relaxed. SWIm began taking magnesium supplements and taking alka-seltzer, sodium bicarbonate before taking the Adderall. Swim also took it at the end of the day and stayed up all night. However, instead of feeling calm, SWIM now feels a tightness in his chest and trouble taking full breaths. He no longer feels relaxed like he used to. Could it be because of the sodium bicarbonate, or perhaps an Adderall break would be in order. It seems like the sodium bicarbonate made it infinitely stronger, but not in the good focused way but instead the blood pressure hard to breath, chest tightness sort of way. Any idea what could have set this off or any experiences similiar that can be related? Thanks
