I used to be hardcore meth head for a long time. I quit for 2 yrs and have done it a little over a dozen times recently. Several days ago I injected some and I didn t get high just really bad tight painful chest and constant feeling of indigestion. My heart periodically skipping beats however it s not racing nearly as fast as it would on an enjoyable high! Happens every single time I do it now..ill do a good amount and still eat and sleep just in a lot of discomfort! What s happening to me?!
