Hiya Hope/Faith. <---- 2 very good qualities
First issue is getting off the medication, and hopefully whatever the medication was for, the underlying issue has resolved for you. That written, if the meds were largely responsible for the weight gain, now that they are discontinued, that catalyst is gone from the equation. I hope that is what you are narrating here.
The above written, there are some positive notes in your post. That you've dieted successfully (ww) before, it shows that your body is capable of letting go of the excess weight. Also, while exercise facilitates weight loss, there is a quote that goes around here on the board that diet is for weight loss, exercise is for fitness. I hope I'm quoting that right. Exercise can be added later and gradually and something that doesn't hurt your legs.
Next, you're ready and you want some advice on how to proceed since WW doesn't fit into your budget. The obvious answer is...do you still possess your WW materials? There are many people who follow older ww programs without going to meetings, and you can get support for that in the WW section of the forum.
Alternatively, you can locate a website for weight loss, like fitday, livestrong, loseit, caloriecount, and input your current age, height, weight, etc. and find out how many calories it takes to maintain your current weight, then subtract up to 500 calories from that total and start eating according to that caloric need. You can go to mypyramid.gov and find out a wealth of info as well. Plan some generic meals and snacks that you can swap out. For instance, fruit smoothie for breakfast, or banana and peanut butter, or oatmeal and fruit, or egg and toast, etc. Plan some lunch salads with protein and dressing. Plan generic dinners, or just plan balanced dinners and have only 1 plate. For instance, pizza isn't the best, but a slice of pizza paired with a salad can go far in aiding weight loss.
Calorie counting is a great way to go. I started this year just making better choices, then joined WW PPlus at work, and I wasn't thrilled with the results, so I started counting calories totally by fluke while looking to kick up my loss efforts. It has been a successful process. I lost 20 pounds since late July. Since Thanksgiving I've been maintaining. I plan to kick up my efforts any day now....
Diet smart, not hard <--- that means don't do anything drastic, because a) it isn't necessary and b) it is counterproductive ultimately. All you need is a calorie deficit up to 500 less than your daily consumption now. When you get that figured out and create a plan, you need to follow through. That you've got a mindset to do it right now, I'd say you're motivated.
You will find a wealth of support and information here. You'll get suggestions on what diets to follow and you need to make the best informed decision that works for you.
I wish you good luck and success.
