I'd highly recommend that you see your doctor right away regarding your medication concerns. Winging it can be dangerous. Bear in mind that nobody ever "wants" to take any medication, so you don't have any special corner on that market. But what you want, and what your doctor wants for you as well, is to restore as much function as possible, under the circumstance of illness.
It is especially important to keep Raynaud's under great control, because each episode is probably worsening the disease process. So by avoiding attacks (through medication or lifestyle changes or both combined) you might actually be improving your overall health, and most especially, sidestepping problems such as ulcers and amputations.
It's a constant battle for all of us, though, as to weighing the medication versus its effectiveness versus its side effects! Our doctors are there to help us manage that process. Also, some medications do only build up slowly and many need to be discontinued very slowly, lest even worse side effects occur. This is the time to lean on your doctor and work very closely with them.
A point that I understand nearly nobody gets until it is too late, is that doctors can and do rate patients as to whether or not they are "compliant". Compliant doesn't mean doing exactly everything they suggest, but it does mean following agreed-upon treatments to the letter and discussing any proposed changes with them ahead of time.
Should the time ever come when an enormously expensive, life-saving treatment might be called for, such as a stem cell or organ transplant, doctors take an extremely close look at whether or not the patient is compliant, and they have every right in the world, and typically use it, to deny such treatments if they feel there is a chance the patient might not follow aftercare instructions, which might entail studiously taking many medications with enormous side effects, dutifully completing every bit of physical rehab, etc.
My late husband was extremely fortunate in that he had a sterling record of always following doctors orders, or discussing it with them whenever he wanted to have changes in his treatment made. So he absolutely passed the compliance test for his lung transplant.
So I strongly recommend that those of us who might be faced with needing lavish treatments in the future be as compliant as we possibly can, so that we build up a reputation of being worthy of special consideration for priceless treatments. In addition to that, it is just a good health habit to discuss our medication pros and cons with our doctors and our pharmacists both before and during treatment.
I have to admit that I have been noncompliant on a few things in the past, when it made good sense to me and when I knew for a fact there would be no adverse effects from stopping the meds. And I made a full confession at my next medical appointment. I must say, most doctors figure, if we were able to go off a medication and are happy about it, then they are happy about it, too, as obviously it either wasn't a very bothersome symptom, or the side effects outweighed it, so it's not like you can typically expect a lot of push-back on it.
So we can provide some input, maybe helpful or maybe not, but the real discussions need to be between you and your doctor. Remember it is okay to ask your doctor for permission to experiment with dosages! I have had permission for variances, within certain parameters, for many medications, and I will often discuss in advance what I should do if I want to discontinue a medication.
Nobody wants to take any medication (if they are in their right mind), but nobody wants to be sick, either! You didn't volunteer for this but you need to either accept some symptoms or treat them, there is no option for magically reverting to pure health, unfortunately.
