Cold fingers, cold flushes, fatigue, asthma flair ups, body shakes, light headed, numb/tingly fingers, sore joints, heart palpitations etc?

These are all side effects of amphetamines. Sometimes when on amphetamines (like adderal, dextrostat, dexedrine, etc.), you may feel a boost of energy, be more talkative, have a loss of appetite, and the worst is when you can't sleep/don't sleep enough.

Limit the amount of dextroamphetamine you take; if you don't NEED to take 5mg 2x a day to focus, don't. Force yourself to eat. If you can't eat, drink a smoothie/milkshake or a v8 to get some nutrients in you. This will help eliminate the body shakes, light headedness, numb/tingly fingers, sore joints, and heart palpitations.

Are you sleeping enough? Sleep is KEY when on amphetamines. Sometimes users will stay on their amphetamines for 2-3 days with no sleep and feel fine, then BAM, they cannot hardly walk without having a pounding heart and feeling like they are about to faint.

The cold fingers, cold flushes, and probably cold feet/toes are just a side effect of any amphetamine and you should not worry TOO much about this, unless they are turning very purple or you are significantly losing feeling.

None of these side-effects are VERY serious in my eyes (I am not a doctor) but I am confident that most/all can be eliminated with a combination of a good amount of sleep, a healthy and regular diet (even if you aren't hungry, EAT!), and possibly a "beta blocker" (ask your doctor about this one).

If you feel your heart rate or blood pressure is too high and you become dizzy/extremely lightheaded, SIT DOWN and let your heart rate slow, drink a v8 or gatorade, eat a protein or breakfast bar, and this should help. Again, the KEY is sleep and a healthy diet. Be SURE to stay hydrated at all times; amphetamines are known for making people not feel thirsty when they are dehydrated.

I am not a doctor (but am studying at a top university to become one right now) so take my advice for what it is worth.

As someone else has pointed out it is highly likely that all these symptoms are side effects of dexamphetamine (prescribed or not). There is a very easy way to find out - stop the drug for a couple of weeks.

The use of this drug as an appetite suppressant represents marginal quality medicine, at best.

Most of those side effects you're talking about happen only in the first couple of weeks... and as I said... these symptoms JUST appeared... so can one person NOT blame my medication for this... if it was... this would have happened from the first time I began taking them... not 5 months later.
